ABSTRACT:
An electron tube, such as a streak tube, is equipped with a gate element for gating unnecessary photoelectrons to prevent them from appearing as a pseudo output signal. A deflection voltage of main deflection plates (typically travelling-wave type) is delayed by a predetermined time and provided to the gate element. The gate element may be shifting deflection plates for sweeping the photoelectrons in a direction perpendicular to the main sweeping direction, a microchannel plate for multiplying the photoelectrons, or a photocathode.
