Investigation about high performance photo cathode for streak cameras

点击翻译按钮获取中文摘要

I have developed a new method that can determine temporal resolution of an X-ray streak camera by observing temporal spread of single photon events on the streak camera. By using the method, I have investigated dependence of the temporal resolution on the X-ray photon energy. I have also developed a 'multi array photocathode' that can investigate the dependence of the temporal resolution and the photoelectron yield on the thickness of the photocathode.
