It Takes a Village: Documenting the Contributions of Non-Scientific Staff to Scientific Research [Slides]

Science, especially large-scale basic research, is a collaborative endeavor, often drawing on the skills of people from a wide variety of disciplines. These people include not just scientists, but also administrators, engineers, and many others. Fermilab, a Department of Energy National Laboratory and the United States’ premier particle physics laboratory, exemplifies this kind of research; many of its high-energy physics experiments involve hundreds of collaborators from all over the world. The Fermilab Archives seeks to document the history of the lab and the unique scientific research its staff and visitors perform. Adequately documenting the lab’s work often requires us to go far beyond things like the writings and correspondence of scientists to also capture the administrative and social histories of the experiments and the context in which they were performed. At Fermilab, we have sought to capture these elements of the lab’s activities through an oral history program that focuses on support staff as well as physicists and collection development choices that recognize the importance of records documenting the cultural life of the lab. These materials are not merely supplementary, but rather essential documentation of the many types of labor that go into the planning and execution of an experiment or the construction of an accelerator and the context in which this work is performed. Any picture of these experiments and accelerators that did not include this type of information would be incomplete. While the importance and richness of this material is especially pronounced at Fermilab due to the massive size of its experiments and accelerator facilities and its vibrant cultural life, the fruitfulness of these collecting efforts at Fermilab suggests that other archives documenting modern STEM research should also make sure the contributions of non-technical and non-scientific staff are preserved and that researchers interested in this subject should not neglect such sources.

The Giants of the Nuclear Testing Era: The Works of Robert K. Osborne

Dr. Robert (Bob) Kidder Osborne was a key physicist and nuclear weapons designer—a giant, in fact, in the sense of Isaac Newton’s use of the term—at Los Alamos National Laboratory (LANL) during the days of weapons designing and testing (1943–1992). (See figure 1.) His career began a few short years after the end of World War II, in August 1949, and spanned over 30 years. He retired from the Laboratory in March 1981. During his career, the United States was designing, building, and testing new nuclear weapons at a prodigious rate. Most of these designs were tested using full-scale nuclear tests (like Operation Plumbbob - Franklin Prime, shown in figure 2). Designers, like Osborne, relied on the results of these tests to prove, and improve, their designs. These improved designs led to developing weapons that contributed to a growing stockpile, which reached its numerical peak in 1967.1 Osborne was a major figure in the development of these advanced weapons designs. He was also largely responsible for the Laboratory’s development of one-point safety, hydronuclear testing, and he was the lead designer of the primary for the W76 nuclear warhead, which is the most numerous warhead in the current U.S. stockpile. Osborne was also an important mentor to many of the Laboratory’s weapons designers.

Closeout Report for CTEQ Summer School 2017

The 2017 CTEQ school was held on the campus of the University of Pittsburgh during July 18-28, 2017. The school consisted of eight days of lectures and discussion where students interact closely with distinguished experts with a broad range of expertise. The CTEQ schools have proven to be extremely useful for students involved at both the Intensity Frontier and the Energy Frontier. The audience for these schools is primarily the younger generation of high energy elementary particle physicists—typically advanced graduate students and postdocs, and are roughly evenly divided between experimental and theoretical disciplines. The CTEQ schools provide the participants with a deeper understanding and improved competency of the fundamental ideas, tools, and techniques that serve as the foundation for all our current investigations of the Standard Model (SM) and beyond. The broader impact is conveyed through the students’ strengthened awareness of the context of their research in the overall endeavor of fundamental physics. The interactive nature of the schools encourages the skills necessary for communicating the excitement and results within collaborations, and also to the wider public. Traditionally, the CTEQ Summer Schools take place in the US in alternative years. In the other years, the Schools are organized by an Institute outside the US. Thus the US school funding is requested bi-annually.

Characterization of Backgrounds for EXO

Neutrinos are fundamental particles that are all around us in nature. While neutrinos do not make up the building blocks of matter, they are an important byproduct of the fusion process that makes the sun burn. Because neutrinos are so light in mass, they almost exclusively interact with the weak force in nature. As such, they provide a unique probe for understanding the weak force. The heaviest mass of the neutrino is still so much lighter than all the other charged quarks and leptons that it hints at the possibility that their mass is produced by a different mechanism than the Higgs boson. How can we study these fleeting objects? This is the challenge for neutrino physicists, and we continue to push the limits of the experimental techniques further and further. Neutrinoless double beta decay is a unique probe of neutrinos that will attempt to answer the question of whether the neutrino is its own anti-particle (Majorana), what it's absolute mass is and if observed, we will see violation of lepton number which will lead the way to new physics. Discovering neutrinoless double beta decay will be exciting but still left to be answered will be what the mechanism is that causes the decay. Understanding this mechanism will also give us more insight into the weak force or new forces at work in the universe. The current experiments are attempting to measure the decay half-life at the level of 1025-1026 years. In order to do this (and better in the future), it is critical to eliminate as many radioactive background processes as possible by shielding from external radioactivity and reducing the internal radioactivity of the detector. This report discusses measurements performed to study potential backgrounds due to neutrons interacting with 136Xe that could affect experiments such as EXO-200 (Enriched Xenon Observatory - 200 kg) and nEXO (next Enriched Xenon Observatory) and KamLAND-Zen.

UW Translational Imaging Biomarker and Therapeutic Development

The development and validation of radiotracers is a critical step in the clinical translation of molecular imaging and theranostics to support personalized medicine. The proposed program is to support such efforts by an interdisciplinary team of investigators at the University of Washington (UW) and Fred Hutchinson Cancer Research Center (FHCRC) and to provide opportunities for trainees to learn the spectrum of translational research in imaging biomarkers and therapeutic development. The proposed translational research projects include "Preclinical Evaluation of PET Imaging for Use in the Translation of Targeted Alpha Therapy of Blood-Related Cancers to Clinical Studies" (Project 1-Wilbur, leader); "Hypoxia Imaging: Radiopharmaceuticals, Preclinical Studies, Mechanisms and Clinical trials" (Project 2-Krohn, leader); and "Diagnostic Applications of Radiolabeled Biologics in Solid Tumors" (Project 3-Minoshima, leader). These projects use radiotracers with long half-lives, such as F-18, Zr-89, I-124, and At-211, that can potentially be handled commercially if translation research is successful. The proposed research method is to use an interdisciplinary 'team' of expert investigators and trainees working on a specific project for 1 or 2 years along the timeline and milestones set by the Program Directors. Each team includes 1) a clinician expert; 2) a radiochemistry expert; 3) an imaging or radiation therapy expert; 4) a physicist; 5) trainees; and 6) a UW technology transfer officer. Two groups of trainees will be involved: clinical and basic science (radiochemistry) trainees. Clinical trainees will be recruited from 3 training programs: Nuclear Medicine Resident Program; Radiology Residency Program; and Residency Program in Radiation Oncology. Basic science trainees will be graduate students from degree-awarding departments (chemistry, material sciences, bioengineering) or post-doctoral students (radiology, radiation oncology, or collaborating departments). A goal of training is to develop future investigators who will be able to conduct independent translational research with knowledge and expertise earned in this interdisciplinary team environment. To address clinically relevant questions, the program will organize regular brainstorming meetings participated by clinicians from various medical disciplines; program investigators; trainees; technology transfer officers to discuss medical questions, relevant targets, and technical feasibility. UW provides outstanding research and clinical facilities and resources that can be accessed by investigators. The Departments of Radiology and Radiation Oncology at UW have been at the forefront of translational imaging and therapeutics research efforts in cancer, neurological disorders, and cardiovascular diseases. This funding opportunity will solidify ongoing efforts of interdisciplinary collaborations at UW into a cohesive program that will train a new generation of investigators. This will, in turn, accelerate the translational potential of new radiotracers by rapid developments of proof-of-concept and first-in-man studies along with in vivo validations in a clinically relevant context.

From Nucleons to Nuclei: Enabling Discovery for Neutrinos, Dark Matter and More

Neutrino interaction uncertainties are a limiting factor in current and next generation experiments probing the fundamental physics of neutrinos, a unique window on physics beyond the Standard Model. Our understanding of the elementary neutrino-nucleon amplitudes at the heart of the neutrino interaction program relies on experiments from an earlier age whose statistical and systematic precision are insufficient for current needs. The workshop brings together physicists with a diverse range of expertise to discuss the status of neutrino-nucleus scattering and to explore (i) the quantitative impact of better constraints on the elementary amplitudes; (ii) the scientific impact of a new hydrogen or deuterium target experiment; (iii) the optimal design and technical feasibility of a new hydrogen or deuterium target experiment; and (iv) complementary constraints on the elementary amplitudes from other methods. The tools and techniques required for understanding neutrino-nucleus interactions are common to many problems at the interface of particle and nuclear physics. The workshop will discuss new developments and prospects for related topics and new physics searches, including dark matter interactions with the Standard Model and neutrinoless double beta decay.

Novel, Low-Cost, Light-Weight High Efficiency (H*10 Capable) Neutron Detector-Dosimeter

The goal of this project was to design, develop and validate a novel, spectroscopy enabled H*(10) neutron dosimetry system based on the tensioned metastable fluid detector (TMFD) sensor technology. The project team consisted of staff from Oak Ridge National Laboratory (ORNL), Purdue University (PU) and Sagamore Adams Laboratories, LLC (SAL). PU-SAL staff were tasked with the design, development, construction and testing of the H*TMFD hardware and software, along with developing the control and data acquisition software for comparison of predictions from H*TMFD against a commonly accepted and widely used industry standard system; for this project, the Li-I detector coupled to bonner spheres (LiI-BSS) system manufactured by Ludlum, Inc. was utilized as the reference (“gold”) standard – similar in terms of neutron spectroscopy enablement to another industry recognized, albeit, significantly higher cost (est. $300K) system referred to as “ROSPEC” (from BTI, Inc., which was not available for this project). ORNL staff were tasked with providing field-relevant guidance, apparatus and facilities for acquiring data against calibrated neutron sources, and comparing results of H*TMFD against LiI-BSS system predictions in a series of blind-tests conducted at ORNL. Over the course of 12 months, the PU-SAL-ORNL staff successfully accomplished the proposed technical and administrative tasks, inclusive of engaging in outreach to potential users of this technology in the DOE-wide infrastructure. The proposed tasks were successfully accomplished in timely manner; the follow-up type tasks pertaining to SBIR type Phases 2-3 were discussed and are initiated, inclusive of filing for intellectual property (IP) disclosures and possible patent filings by PU’s Office of Technology Commercialization (OTC). Two H*TMFD system architectures (see Exhibits 1 & 2 in the report) were developed and constructed for hand-portability by health-physicists (HPs) – the HP-H*TMFD, and the H*TMFD system which consists of a side-by-side mounted array of 4 TMFDs of 3 different sizes in sensitive volume (including one with borated fluid) that now simultaneously enables neutron energy spectroscopy: single bin for < 0.1 MeV, and 152 energy bins in the 0.1-15.2 MeV range; H*(10) dosimetry from ~5 μRem/h towards 10 R/h ranges. Several experiments were conducted using neutron sources in various configurations (shielded and unshielded). In direct comparison against the LiI-BSS industry standard (acquiring data for 26h each source), the H*TMFD system (acquiring data for ~6h for each source) offered H*(10) dose predictions for the most part accurate to within +/-10% for dose rates in the 100-300 μRem/h range. The LiI-BSS was impractical to use under ultra-low (~10 μRem/h) dose rate space, as also another metering device used at ORNL (Ludlum 4241L non-spectroscopy enabled) for which the lower limit is set by the manufacturer at 100 μRem/h. The enablement for efficient use in timely manner at the 10 μRem/h levels is deemed to be a strong enabling factor for H*TMFD for use in the DOE-nuclear laboratory arena. In terms of weight, the HP-H*TMFD weighs under ~5-7 lb.; the H*TMFD system weighs ~35-lb. As such, it is ~1/4 the weight of an LiI-BSS system weighing ~120 lb (LiI detector with 6 bonner spheres) and, ~1/2 the weight of ROSPEC. As a result of this activity, two involved post-doctoral student staff have now transitioned their knowledge and experiences to DOE’s Pacific Northwest National Laboratory (PNNL). A PU graduate student has also benefited from this project work which formed a principal basis for his Ph.D. dissertation work (in progress).

Radiological Consequences of Beam Loss on Beamline Front End Collimator during Top-off Injection into the Storage Ring

The primary radiological safety concern for the top-off injection, with the beam line front end safety shutters open, is the scenario where electrons could be conveyed down to the beam line through the front end due to the erroneous combination of lattice magnetic field settings and beam energy. It is of paramount importance to ensure that such events are of remote possibility. Particle tracking simulations by the NSLS-II Accelerator Physicists have shown that by a set of interlocking requirements of the lattice magnetic fields and by the implementation of physical apertures, the errant electron beam can be confined to the front end components within the storage ring.

Collaborative Research: Experimental and Theoretical Study of the Plasma Physics of Antihydrogen Generation and Trapping (Final Technical Report)

The charge-parity-time (CPT) invariance principle and the weak equivalence principle (WEP) undergird our current understanding of Nature. CPT, which is based on only Lorentz invariance, locality, and spin-statistics, is basic to local relativistic quantum field theory (QFT) models of physical laws. Testing established principles like these is a long-standing and honorable tradition in physics. Beginning with Newton’s Laws, many firmly established laws have been superseded, often to the great surprise of contemporaneous physicists. Certainly, CPT rests on firmer grounds than the earlier widely believed, but erroneous principles, of parity (P) and charge-parity (CP) invariance, but this does not necessarily make CPT inviolable. Tests of CPT confront the entire framework of QFT, and are quite distinct from most other “beyond the Standard Model” searches, which look for new physics within the QFT framework. With the failure, so far, to find new physics at the LHC or in dark matter searches, the motivation to test QFT itself is urgent. The revolutionary consequences of CPT and WEP violation would be so great that these principles are under intense scrutiny in many different systems. Here we focus on tests of CPT and WEP that employ antimatter, specifically antihydrogen. Such tests are difficult to realize experimentally, but constitute some of the simplest and most profound matter-antimatter comparisons that can be performed. Antimatter particles have been investigated since the prediction and subsequent discovery of the positron in the 1930s. That early discovery motivated the search for the antiproton, culminating in its creation and detection in Berkeley two decades later. As far as we know today, particles and their antiparticles share identical properties except for the sign of their charge. Antihydrogen is the simplest antimatter system—it is the antiparticle of the simplest atom, hydrogen. Differences between the spectra of the two are forbidden by CPT. The weak equivalence principle (WEP), demands that matter and antimatter accelerate identically in a gravitational field. WEP has never been subjected to a direct, free fall test using antimatter. Because of the weakness of the gravita tional force, direct antimatter WEP tests must employ a neutral particle, of which antihydrogen is the simplest to obtain. There are reasons to suspect that something is amiss with our understanding of antimatter. All generally accepted theories of the Big Bang predict that roughly equal amounts of matter and antimatter should have been created. Instead, very little antimatter has been observed in the Universe. This baryogenesis problem is arguably the most fundamental issue with the theory of the Big Bang. Its resolution may come from the discovery of enhanced CP violation, but could also come from CPT or WEP violation.

The NSLS-II Alignment Coordinate System Conventions

For NSLS-II construction activities, a construction coordinate system is established with certain connections to geodetic NY State Plane Coordinate System, while physicists design the lattice and layout of accelerator and beam lines in a relatively dependent virtual space with their beam following coordinate system. In engineering design process, mechanical drawing designers, and beam line experts may both have their own coordinate system in a self-convenient manner. This situation will bring out problems of consistency and eventually lead to potential chaos for survey and alignment work. Therefore, it prompts to establish coordinate conventions recognized by all the relevant groups in order to smooth the coordinate processing flow when executing the alignment task according to specific design. Here descriptions about several existing coordinate system will be delineated and the definition of accelerator alignment coordinate system will be emphasized. The rotation and translation mathematical parameters will be given to allow for easy transformation. All the units are in meters. A programming code has been written to deal with a key requirement of integrating components’ fiducials into storage ring coordinate system. The parameters and code can be validated and tested by relevant groups.

Building an open source software ecosystem for cross-disciplinary plasma research and education

Software is crucial to all areas of modern plasma science research. Laboratory plasma physicists use software to interpret plasma diagnostics, analyze experimental results, and glean insights using advanced techniques from data science. Space scientists use software to reduce and understand in situ observations. Numericists use software to simulate the behavior of laboratory, heliospheric, and astrophysical plasmas, and then analyze or visualize the results. Theorists use symbolic manipulation software to perform or check derivations. Cross-disciplinary research and cross-comparisons between experiments, observations, simulations, and theories all require software. Despite our heavy reliance on software, funding agencies have traditionally had few avenues available to support development of general purpose research software infrastructure.

Building Towards Discovery: Preparing for New Physics at the LHC [Final papers]

Particle physics today is at a crossroads. The Standard Model (SM) has survived four decades of experimental scrutiny and spurred multiple landmark discoveries, culminating with the 2012 discovery of the Higgs boson at the Large Hadron Collider (LHC). Yet we know that this model is incomplete. We live in a universe dominated by matter and energy unaccounted for by the SM– and the Higgs boson itself is improbably light. It falls to the current generation of high-energy physicists to go beyond the model and enter a new era of discovery. Andeen is leading a new research group at the University of Texas at Austin (UT-Austin) that is endeavoring to reveal novel physical phenomena through the discovery of new particles with the ATLAS detector at the LHC. A key element of our experience thus far has been collaborating closely with theorists to identify both interesting new physics models. In addition we work closely with electrical engineers in detector development. Our approach is therefore unique in its integration of theory, analysis and instrumentation, and is encapsulated in a three-pronged strategy. First is the essential task of analyzing our rapidly expanding dataset. I am directing my group in searches for vector-like quarks (VLQs). Should they exist, these hypothetical particles would indicate physics scenarios beyond the SM. Experimental constraints suggest VLQs decay preferentially to a third generation quark and a Higgs, W or Z boson. Today at 13 TeV, both multi-lepton (electron and muon) and jet substructure signatures are sensitive to identifying the VLQ decay products. The large Run 2 dataset (collected through 2018) of up to 150 fb -1 will allow us to simultaneously use multi-lepton signatures with jet-substructure in searches for new physics. UT-Austin is well positioned to be a leader in this area. Prof. P. Onyisi’s postdoctoral researchers and graduate students are searching for ttH signatures in three- and four-lepton channels and we benefit from their experience. We are also aided by the availability of the Texas Advanced Computing Center, which provides us with easy access to several high performance computing (HPC) systems. My previous experience in VLQ searches propels the work today. I have published both the first investigation into the single production of top partners (signatures of composite Higgs Models) of any LHC experiment 1 as well as one of the first analyses utilizing jet-substructure techniques to search for the single production of vector-like quarks. 2 Adding to this is my group’s work with the Liquid Argon (LAr) calorimeter, the primary instrument we use in detecting electrons. Second, my group is contributing to the operations of the LAr calorimeter while preparing to install and commission new electronic hardware (the Phase 1 upgrade) to this crucial component of the ATLAS detector. I have played a leading role in the development of a critical, radiation-hard, high-speed Analog-to-Digital Convertor (ADC) that is essential inselecting data collected by the LAr calorimeter. 3 This upgrade will improve the e!ciency with which we can select events in our detector. Postdoctoral researcher N. Nikiforou (based at CERN May 2016 onward) and graduate students (one based at CERN from the start of 2018 onward, with one additional graduate students from summer 2018) are growing our already deep experience in the operation of the LAr calorimeter to prepare for installation and commissioning of the new trigger readout in 2018-2019. My group will then be positioned to be the first to exploit the potential of the improved triggers in our multi-lepton searches for new physics. Third, a suite of preparations for a major detector upgrade, scheduled to be completed in 2024, are underway. My group is building hardware that will improve the electronic readout of the ATLAS detector. I am partnering with a group in the Electrical and Computer Engineering (ECE) Department at UT-Austin (Prof. N. Sun) to employ his work at the cutting edge of ADC research. We will support an ECE grad student for the layout of this design, and collaborate with engineering groups at Nevis Laboratory and the Electrical Engineering Department (Prof. P. Kinget) at Columbia University to integrate our ADC with gain selection circuits. We will provide this critical component of the ASIC at the challenging boundary of the analog and digital signals in the LAr calorimeter readout chain. Furthermore UT-Austin will lead the testing of this device during development and production (approximately 55,000 four-channel chips). This effort compliments my work as the deliverables manager for the LAr front-end ASICs for the US ATLAS HL-LHC project and strengthens the US commitment to that upgrade.In so doing, my group at the UT-Austin will be at the forefront of efforts to probe the structure of the universe to an unmatched degree both at the current LHC and with its future upgrades. Through both the ongoing analysis of data at the ATLAS detector and improvements to the detector itself, an answer to what lies beyond the SM may come within our grasp. My background in instrumentation and analysis allows my group to establish a singular research effort on the ATLAS experiment. In addition to answering fundamental questions about the subatomic world, the technologies developed could advance the broader scientific community and result in valuable spin-offs.

Creating a Dedicated Plasma Physics Review Journal to Promote Cross-Fertilization Across Subfields

This white paper identifies the pressing need for a high-quality review journal dedicated to the field of plasma physics. As the community of plasma researchers has expanded over the last decade, it has also become increasingly specialized and fragmented. Scientists focused on one particular subfield have no easy way to learn about major developments in other areas of plasma physics. This difficulty has resulted in the duplication of work and missed opportunities for cross-fertilization of ideas and techniques. The establishment of a dedicated review journal, similar in character to the well-known Annual Review series, would greatly increase communication among plasma physicists and keep the community apprised of the latest breakthroughs in the field.
