Highlights of the 2016 Summer Laboratory Student Intern Program at Sandia National Labs [Slides]

Combined picosecond (10 -12 s) and femtosecond (10 -15 s) laser pulses can give sensitive, low-noise measurements of important quantities in reacting flows, such as species concentrations and temperature. Emmanuel’s work focused on the development of an instrument for tailoring the time profile of picosecond laser pulses for use in nonlinear optical spectroscopic methods created from broad bandwidth femtosecond pulses. In addition to constructing the device, Emmanuel produced a LabView-based automation code, building off skills he developed in a previous CCI internship at Sandia.

Department of Energy Office of Science Graduate Student Research (SCGSR) Program Mid-Award Project Report

Three-quarters of the total mass of the universe is believed to be ”dark”, meaning that it does not interact with light; it’s presence has only been inferred through astrophysical observations. Because this so-called dark matter has never been observed directly, the question of its identity has become one of the most prominent unresolved mysteries in physics. With many answers ruled out, a direct observation of dark matter is certain to uncover new physics beyond the Standard Model, making it an enticing area of study.

Project Description for Student Symposium 2022: Modeling Approach to Critical in the Upcoming CERBERUS Experiment

The Critical Experiment Reflected By copper to BettEr Understand Scattering [CERBERUS] is an integral experiment that will be executed at the end of FY23. The experiment is designed to study the intermediate energy range, in particular elastic and inelastic scattering of neutrons in copper. Approaching criticality safely is of utmost importance, and having a computer mode is a useful tool when determining changes that can safely be made to the experiment. Multiple simulations are needed to analyze the approach to critical, and manually creating MCNP input files is both tedious and error prone. To solve this problem, a python script was created to develop and run these input files.

Summer Student Internship: Experimental and modeling experiences

My internship at the Los Alamos National Laboratory has been an information-filled summer. Loren Espada-Castillo brought me into her project and helped mentor and guide me through the summer. The project that I was brought into was the process of shooting materials with electrons. The electron beam we used conducts a series of shots in which electrons are generated and then fired towards a target, the sample holder. The sample holder holds either a single sample or three samples. The sample holder also consists of multiple calorimeters surrounding the sample/s. The goal is to shoot certain materials and then analyze how they react to the exposure of the electrons. We shot titanium, which was meant to serve as a containment vessel window.
