Electroproduction of neutral pions in the Hall A at the Jefferson Laboratory; Electroproduction de pions neutres dans le Hall A au Jefferson Laboratory

The past decade has seen a strong evolution of the study of the hadron structure through exclusive processes, allowing to access to a more complete description of this structure. Exclusive processes include DVCS (Deeply Virtual Compton Scattering) as well as hard exclusive meson production. This document is particularly focussed on the latter, and more particularly on exclusive neutral pion production. In this thesis is described the analysis of triple coincidence events H(e, e'γγ)X, which were a consequent by-product of the DVCS experiment which occured during Fall 2004 at Jefferson Lab Hall A, to extract the ep → epπ 0 cross section. This cross section has been measured at two values of four-momentum transfer Q 2 = 1.9 GeV 2 and Q 2 = 2.3 GeV 2 . The statistical precision for these measurements is achieved at better than 5 %. The kinematic range allows to study the evolution of the extracted cross section as a function of Q 2 and W. Results are be confronted with Regge inspired calculations and Generalized (GPD) predictions. An intepretation of our

Los Alamos National Laboratory and Lawrence Livermore National Laboratory Plutonium Sustainment Monthly Program Report, October 2012 (Revision 8)

In October of 2012 the Plutonium Sustainment program at LANL completed or addressed the following high-level activities: 1) Completed Pollux shipment to DAF in early October in accordance with the Gemini Core Team's schedule. Unpacked Pollux at DAF and supported Gemini team in various tests and inspections. Pollux test and measurement results were all acceptable. Pollux is expected to g to U1A in November. Pu Sustainment no longer has any obligations associated with the Gemini experiment. 2) Presented to Dr. Cook on the successful assembly of the Pollux experimental device as part of the Gemini series. 3) Supported the release of the FY12 Pu Sustainment Program Implementation Plan. 4) Established the FY12 program baseline and allocated funds accordingly. 5) Meetings: a. Hosted the Pu Containment 4 th Quarter Program Review; b. Hosted the Power Supply PRT; c. Traveled to KCP for the W87 Pit IPT. All four MRT L2 Milestones (4622-4625) associated with Plutonium Sustainment are on track for success in FY13.

Independent Verification of the Central Campus and Southeast Laboratory Complex Building Slabs at Oak Ridge National Laboratory, Oak Ridge, Tennessee

Oak Ridge Associated Universities/Oak Ridge Institute for Science and Education (ORAU/ORISE) has completed the independent verification survey of the Central Campus and Southeast Lab Complex Building Slabs. The results of this effort are provided. The objective of this verification survey was to provide independent review and field assessment of remediation actions conducted by SEC, and to independently assess whether the final radiological condition of the slabs met the release guidelines.

MEMORANDUM OF UNDERSTANDING between Los Alamos National Laboratory (LANL) and Savannah River National Laboratory (SRNL) for Analytical Chemistry Support for Oxide Production Samples

This MOU establishes the responsibilities and requirements for the packaging and transport of plutonium dioxide (PuO 2 ) samples for shipment from LANL to SRNL. The scope includes the shipping, packaging, quality assurance (QA), inspection, and documentation requirements to successfully obtain the chemical and isotopic characteristics of the PuO 2 . The requirements in this document are necessary, but not sufficient to execute this work and do not imply exemption from contractual requirements at either site. This document is not intended to specify all of the processes and procedures necessary to execute this work. This MOU also establishes appropriate requirements, goals, and expectations. Each party will establish a technical point of contact (POC) who will be responsible for addressing issues as they arise

Lawrence Livermore National Laboratory and Sandia National Laboratory Nuclear Accident Dosimetry Support of IER 252 and the Dose Characterization of the Flattop Reactor at the DAF

In support of IER 252 “Characterization of the Flattop Reactor at the NCERC”, LLNL performed ROSPEC measurements of the neutron spectrum and deployed 129 Personnel Nuclear Accident Dosimeters (PNAD) to establish the need for height corrections and verification of neutron spectrum evaluation of the fluences and dose. A very limited number of heights (typically only one or two heights) can be measured using neutron spectrometers, therefore it was important to determine if any height correction would be needed in future intercomparisons and studies. Specific measurement positions around the Flatttop reactor are provided in Figure 1. Table 1 provides run and position information for LLNL measurements. The LLNL ROSPEC (R2) was used for run numbers 1 – 7, and vi. PNADs were positioned on trees during run numbers 9, 11, and 13.

Cooperative Research and Development Agreement among Ames Laboratory; NexTech Materials, Ltd. dba Nexceris; and National Energy Technology Laboratory [Abstract]

The CRADA focuses on pressurized testing of Nexceris solid oxide fuel cell (SOFC) stacks in a hybrid configuration with a recuperated gas turbine with the ultimate goal of demonstrating efficiencies in excess of 70% (LHV NG). NETL’s cyber-physical approach will be used to develop and test control strategies before installing the Nexceris SOFC stacks to maximize the chances of success. A successful test will represent a demonstration of the Nexceris stack to endure pressures associated with hybrid operation and the first public demonstration of automated hybrid SOFC/GT technology.
