Abstract
An electron tube device for measuring light pulses generated at a high repetition rate which includes an electron tube, power supply device and deflection voltage generator. The electron tube has a photocathode, focusing electrode, deflection electrodes, slit electrode, dynodes and a collector electrode positioned within an evacuated envelope. The power supply device supplies voltages to the dynodes and to the focusing and slit electrodes, and the deflection voltage generator supplies deflection voltages to the deflection electrodes which successively change in phase with respect to light pulses impinging on the photocathode so that different portions of the light pulses can be successively sampled.
