In the past few years high energy protons (30-50 GeV/c) have emerged
as a top radiographic tool for non-destructive imaging of dense materials.
In particular, it is a leading candidate for tomographic reconstruction
in experiments to study the aging effects in the nuclear weapons stockpile,
part of DOE's Stockpile Stewardship Program.
The LLNL High Energy Physics draws on its experience in high energy
physics experiments and contact with with groups in Engineering and
Defense and Nuclear Technologies to design experiments that will determine
the technical feasibility of proton radiography. The group conducts
its experiments at LANCSE at LANL and the AGS at BNL. The figure
on the right above, shows actual time dependent radiographs of a shocked
metal.
