Abstract
The optical trigger 22 outputs a trigger signal in. synchronization with a pulse beam falling incident on the photocathode 91 of the streak tube 90. The deflection voltage generator 50 applies a pair of deflection voltages to the deflection electrodes 93 and 93' in the streak tube 90. The differential amplifier 60 detects the deflection voltages, and outputs a deflection voltage detection signal. The delay comparator 71 detects a time difference between the deflection voltage detection signal and the trigger signal, and outputs a difference signal indicative of the detected time difference. Based on the difference signal, the voltage control delay circuit 41 controls a delay amount of the deflection voltages to be outputted from the generator 50.
