Abstract

The National Ignition Facility South Pole Bang Time diagnostic uses polycrystalline diamond photoconductive detectors to measure x-ray bang time on capsule implosion shots. The original Laboratory for Laser Energetics PCD design was redesigned to eliminate ringing near the peak of the impulse response, and provide 30 picosecond resolution. The detector design, performance and x-ray laser impulse response tests used to characterize the detector are presented.
