Abstract: Our ability to understand the response of matter at extremes requires detailed knowledge of a materials’ multiphase properties including the location of phase boundaries, details of the phase transitions and their kinetics, and the equation-of-state of the various phases. Although there has been much success in relating the details of the shock-wave profile (shape and evolution) to the material response, traditional diagnostics are limited to interface measurements such as particle velocity and longitudinal stress which have difficulty when the processes and/or materials are heterogeneous. Developments in advanced light sources, X-ray detection methods, and optical radiance methods are all providing unique opportunities for ultrafast, high-resolution, spatially resolved measurements to examine materials during impact loading. An overview of the dynamic compression work on cerium will be presented that was conducted over the last two decades with a focus on more recent X-ray diffraction and optical radiance measurements that are providing invaluable insights into the microstructure and temperature during shock loading. The talk will include a brief discussion of our capabilities at the Institute for Shock Physics (WSU, Pullman WA) and the Dynamic Compression Sector (APS, Argonne IL) designed to probe material deformation dynamically across length scales.
Bio: Prof. Brian Jensen has more than 25 years of experience in the field of dynamic high pressure physics using powder and gas gun systems, explosives, and lasers to examine the dynamic response of condensed matter subjected to high pressures. He graduated from Knox College in 1997 with a B.A. in Physics and Classics, and later from Washington State University in 2003 with a doctorate in Physics. In 2004, he joined the Dynamic Experiments Division at Los Alamos National Laboratory as a technical staff member working in the Shock and Detonation Physics group where he spent nearly 20 years studying the response of matter at extreme conditions. During those years, he served in many roles included as the team leader for the historic Shock Physic team, the Los Alamos lead for the Dynamic Compression Sector, and as the High-Z Project Leader for actinide science in the Office of Experimental Science’s Dynamic Materials Properties Program. Central to his efforts has been the development of diagnostics and facilities dedicated to dynamic compression science including Los Alamos Laboratory’s new Dynamic Equation of State Facility (DEOS) that modernized and consolidated historic shock physics capabilities. He has served as the Chair of the APS topical group on Shock Compression of Condensed Matter (GSCCM), as a member of the Los Alamos Laboratory Scientific Advisory Panel, elected as a Fellow of the American Physical Society, and was awarded the Los Alamos Fellow’s Prize in 2022. In September of 2023, Dr. Jensen joined the Department of Physics and Astronomy at Washington State University as Professor and became the next Director of the Institute for Shock Physics.

MSEE Seminar: Dr. Tim Goorley
The seminar will begin at 3:00 PM ET on Tuesday, March 12, 2024.
Please contact Sarah Preis for connection information.
Bio: Dr. Tim Goorley is the Chief Scientist for Nuclear Weapon Effects at Los Alamos National Laboratory (LANL), a role which guides and directs technical analyses, modeling and simulation capability development, and training. Ultimately these efforts inform LANL senior leaders about mission effectiveness, survivability, and consequences of execution, and ‘The Art of the Possible’. For the past 23 years at LANL, Dr. Goorley has been applying his nuclear engineering expertise to various nuclear weapons detonation related diagnostics, weapons effects, and forensics related missions.
For seven of these years, Dr. Goorley has led groups of ~25 people in their successful support of nuclear weapons missions within the Weapons Physics Directorate at LANL. These missions include assessments of intrinsic radiation, modern and historic diagnostics, radiation shielding, nuclear forensics, criticality assessments, weapons effects, and the development of software used in these analyses. Dr. Goorley’s dissertation topic was the computational evaluation of a new form of brain tumor therapy based on the element Gadolinium and neutron or gamma radiation. For his 6 years as a graduate student, Tim was part of the Harvard/MIT Boron Neutron Capture Therapy (BNCT) human clinical trials team, which used 10 Gy doses of mixed neutron and gamma radiation to investigate the potential therapy of advanced brain cancers. It is this expertise that he continues to leverage to understand the physical impacts that nuclear detonations have on people.
