Roger White wins second award for post-detonation nuclear forensics

Lab physicist Roger White, a designer in B-Division from the Weapons and Complex Integration Directorate, received his second award from the Defense Threat Reduction Agency for his work in post-detonation nuclear forensics.

White was the "top contributor of the quarter" for the third quarter of fiscal year 2013. He led a 55-person multi-lab/agency research team that developed and executed a simulated terrorist nuclear event in the United States.

The event was the second of three elements used to demonstrate the capability of U.S. emergency responders to obtain ground-based, prompt diagnostics that can be used by forensics designers to reconstruct information, such as a terrorist-detonated nuclear device.

"Teams from the Global Security, WCI and Physical and Life Sciences directorates of Lawrence Livermore as well as contributors from Los Alamos and Sandia national laboratories, the Air Force Technical Applications Center, Applied Research Associates, and Weston Geophysical are to be commended for their outstanding teamwork on a very complex effort that yielded highly successful results," White said.

The goals of the program include reducing the amount of time scientists need to reconstruct an event and improving the capability of technical nuclear forensics. The team worked with speed-of-light signals, speed-of-sound technology and radiochemical analysis of nuclear debris to assess and reconstruct the simulated event.

"The vision, leadership and program management of the Defense Threat Reduction Agency and their support have allowed these teams to achieve a remarkable, integrated capability in a relative short period of time and at a minimum cost," White said.

White won his first award for post-detonation nuclear forensics from DTRA in April 2012.
