Streaking image tube with closely spaced photocathode, suppressor mesh, and accelerator mesh

摘要

A streaking image tube having a suppression mesh electrode spaced between the normally provided accelerating mesh electrode and anode. Appropriate potentials are applied to the electrodes so that undesirable secondary emission from the accelerating mesh electrode is returned to that said electrode.PPCROSS REFERENCE TO RELATED APPLICATIONSPP The above-entitled application is a Rule 60 continuation of Ser.
