New type ultra-fast photoelectric radiation detector

A new type of photoelectric detection device with the characters of ultra-fast and wider dynamic linear range was developed. It was used for the measurement of ultra-fast pulse signal. The characteristic parameters of device were studied by pulse xenon lamp and laser etc. The detection system with ultra-fast scintillator was applied in ultra-fast pulse X-ray generator. The experimental results indicate that the detector has ultra-fast time-response. Its further applications will be found in the field of sub-nano-second pulse measurements. (authors)
