Abstract
A high speed light detection tube consists of a planar photoelectron source of transparent type, a photoelectron collection electrode arranged in parallel with the photoelectron source and an acceleration electrode of transmission type arranged in parallel with the photoelectron source in a space between the photoelectron source and the photoelectron collection electrode. The potential distribution has been set so that the photoelectrons passing through the acceleration electrode can be incident on the photoelectron collection electrode at a constant speed or near value.
