Join us for a seminar with Brian J. Jensen of Washington State University, titled “Two Decades of Shock Wave Experiments on Cerium.”

The seminar will begin at 3:00 PM ET on Tuesday, May 7, 2024.

Please contact Sarah Preis for connection information.

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: Brian J. Jensen flyer

Dates: June 11 - 13, 2024 The Defense Threat Reduction Agency (DTRA) uses the Annual Technical Review to review the progress of the MSEE URA. This meeting also provides a forum for the government and corporate affiliates program (GCAP) and science advisory board (SAB) to view the MSEE research activities. Each MSEE principal investigator (PI) will present their technical progress and accomplishments followed by a short question/answer period. This meeting is open to DTRA, MSEE PIs and their graduate students and postdoctoral fellows, and GCAP and SAB members. MSEE PIs (or a designated representative) are required to prepare and present a poster on each of their research tasks. Poster sessions will occur during the afternoon of days 1 and 2 of the Annual Technical Review. VENUE The Annual Technical Review will take place across the street from the Johns Hopkins University Homewood Campus at the Inn at The Colonnade, 4 W. University Parkway, Baltimore, MD 21218.   EVENT REGISTRATION The Annual Technical Review is a by-invitation-only event. The deadline for registration is Friday, May 31. EVENT REGISTRATION NETWORKING AND POSTER SESSION During this year’s ATR, we will host networking and poster sessions at the end of days 1 and 2. On day 1, there will be two networking sessions:

1. A professional development networking session led by former Acting and Deputy Director of DTRA, Major General Randy Manner. This professional development session is only available to MSEE students and postdocs. Additional details can be found here. Professional Development Session Details
2. A networking session open to all other ATR attendees with opportunities for breakout groups by Research Area and Focus area.

On day 2, we will host our poster session, combining all posters in to one session. A listing of the posters will be announced closer to the event. Poster Guidance      Poster Template Food and beverages will be provided at all networking and poster sessions. DINNER BANQUET A dinner banquet will be held on Wednesday, June 12, 2024, at the Inn at the Colonnade. If you plan to attend, please select the banquet option during your registration or contact Christopher Pottillo at [email protected]. Reservation deadline is Friday, May 31, 2024. AGENDA The agenda for this event is currently in progress. The latest draft of this agenda can be found here. EVENT LODGING Rooms have been reserved for this event at the Inn at The Colonnade at a group rate of $179.00 per night. The deadline to reserve rooms is Friday, May 17.
