ABSTRACT:
A system for calibrating the time axis of an X-ray streak tube comprising a light source for generating a train of light pulses and an X-ray tube including a photocathode for receiving the light pulses. Upon receiving the light pulses, the X-ray tube generates a train of X-rays which excite the photocathode of the streak tube causing it to emit an electron beam. The electron beam is scanned by a sweep voltage synchronized with the light pulses and applied across deflection electrodes in the streak tube. The deflected beam impinges on the phosphor screen of the streak tube where the time interval of the streak image is measured.
