Joint Actinide Shock Physics Experimental Research (JASPER)

Photo of JASPERThe Joint Actinide Shock Physics Experimental Research (JASPER) Facility plays an integral role in the testing of the nation's nuclear weapons stockpile by providing a method to generate and measure data pertaining to the properties of materials (radioactive chemical elements) at high shock pressures, temperatures and strain rates. These extreme laboratory conditions approximate those experienced in nuclear weapons. Data from the experiments is used to determine material equations-of-state and to validate computer models of material response for weapons applications. Experiment results are used for code refinement, permitting better predictive capability and ensuring confidence in the U.S. nuclear stockpile.

JASPER is a multi-organizational research facility consisting of Lawrence Livermore National Laboratory, Los Alamos National Laboratory, Sandia National Laboratories, NSTec, and the U.S. Department of Energy National Nuclear Security Administration
