Title: High-Yield Bang Time Detector for the OMEGA Laser

Abstract

A simple, low-cost, high-yield neutron bang time (HYNBT) detector has been developed and implemented on the 60-beam, 30 kJ OMEGA Laser Facility at the University of Rochester's Laboratory for Laser Energetics. The HYNBT consists of three chemical-vapor deposition diamond detectors of different sizes and sensitivities placed in a lead-shielded housing. The HYNBT is located in a reentrant tube 50 cm from the center of the target chamber. The HYNBT has been temporally cross calibrated against the streak-camera-based neutron temporal diagnostic (NTD) for both D2 and DT implosions. The HYNBT has an internal time resolution better than 20 ps and is able to measure bang time for yields above 10^10 for DT and 5 x 10^10 for D2 implosions. The implementation of the HYNBT on the National Ignition Facility will be discussed.
