The National Nuclear Security Administration (NNSA) of the Department of Energy (DOE) is sponsoring the development of the Dynamic Compression Sector (DCS), a first-of-a-kind user facility dedicated to dynamic compression science.  Washington State University (WSU) is leading the effort to develop and build the DCS infrastructure and instrumentation (at Sector 35 on the APS experimental hall floor), in collaboration with the APS; DOE/NNSA National Laboratories (Los Alamos, Lawrence Livermore, and Sandia); Department of Defense Laboratories, including the Army Research Laboratory and Naval Research Laboratory; and academic institutions. The DCS represents an exciting and visionary capability in support of the NNSA’s scientific mission, and offers an opportunity to pursue fundamental science that has not been possible at any synchrotron radiation facility to date.
