Photoconductive detectors with fast temporal response for laser produced plasma experiments

Processes during laser plasma experiments typically have time scales that are less than 100 ps . The measurement of these processes requires x-ray detectors with fast temporal resolution. We have measured the temporal responses and linearity of several different x-ray sensitive photoconductive detec...

Description
Summary:Processes during laser plasma experiments typically have time scales that are less than 100 ps . The measurement of these processes requires x-ray detectors with fast temporal resolution. We have measured the temporal responses and linearity of several different x-ray sensitive photoconductive detectors (PCDs). The active elements of the detectors investigated include both diamond (natural and synthetic) and GaAs crystals. The typical time responses of the GaAs PCDs are approximately 60 ps , respectively. Some characterizations using x-ray radiation from a synchrotron radiation source are presented.
