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 D{sub 2} 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{sup 10} for DT and 5x10{sup 10} for D{sub 2} implosions. The implementation of the HYNBT on the National Ignition Facility will be discussed.
