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 partnering with the Advanced Photon Source (APS) in collaboration with the DOE/NNSA National Laboratories (Lawrence Livermore, Los Alamos, and Sandia), DoD Laboratories, and academic institutions to develop and build the DCS infrastructure and instrumentation at Sector 35 on the APS experiment hall floor.  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.
