Radiation hardening of gated x-ray imagers for the National Ignition Facility (invited).
Perry M. Bell,D. K. Bradley,J. D. Kilkenny,A. Conder,C. J. Cerjan,C. A. Hagmann,D. S. Hey,N. Izumi,J. D. Moody,Alan T. Teruya,John R. Celeste,J. R. Kimbrough,Hesham Khater,Mark Eckart,J. Ayers +14 more
TL;DR: A novel instrument, active readout in a nuclear environment, is described which uses the time-of-flight difference between the gated x-ray signal and the neutron which induces a background signal to increase the yield at which gated cameras can be used.
