X-ray detector with picosecond time resolution

摘要: An X-ray detector for obtaining time resolved signals from intense pulsed sources, such as a fuel pellet during laser fusion process. The has cathode which emits electrons when bombarded by X-rays the pellet. are accelerated an electron accelerator to relativistic velocities and impinge on Cherenkov emitter radiates light. optical system collects focuses radiated light onto image converter streak camera or other fast photodetector provide trace of intensity function time. Time images may be produced recorded using Kerr cell shutter.
