On-line temporal characterization of an X-ray streak camera

A simple system for an on-line temporal characterization of an X-ray streak camera is described. Multiple UV-transmitting fiber optic channels with known relative time delays facilitate measurements of sweep speed in addition to providing a fiducial signal. Results of measurements on variation of sweep speed across the output screen of an in-house developed X-ray streak camera of an average sweep speed of 24.5 ps/mm and a temporal resolution of 7.5 ps are presented.
