The Joint Actinide Shock Physics Experimental Facility (JASPER) is an experimental research facility developed by personnel from Livermore National Laboratory, Los Alamos National Laboratory, Sandia National Laboratories, and Bechtel Nevada. Using a two-stage light-gas gun, JASPER will be used to study the behavior of actinides and other hazardous materials under high pressures, temperatures, and strain rates. These extreme laboratory conditions will approximate those experienced in nuclear weapons, and data from the experiments will be used to determine material equations of state and to validate computer models of material response for weapons applications. JASPER is operated by the Lawrence Livermore National Laboratory for the Department of Energy.
Nested confinement systems assure that radioactive materials are not released into the gas gun building or the environment after target impact. The primary target chamber houses the target material, and a high explosive closure valve traps radioactive contaminants within the chamber after the projectile enters. A secondary containment chamber assures that if any materials escape from the primary target chamber, they will not migrate into the building environment.
