Title:
増幅回路用真空管及びそれを用いた増幅回路
Document Type and Number:
Japanese Patent JP7382338
Kind Code:
B2
Abstract:
A vacuum tube for amplifier circuit includes: a light incidence window that transmits signal light; a photoelectric conversion unit that converts the signal light transmitted through the light incidence window into photoelectrons; an output unit that has an anode, on which the photoelectrons are incident, and outputs a signal corresponding to the incident photoelectrons; and a grid electrode that is disposed in a path of the photoelectrons from the photoelectric conversion unit to the anode and controls the amount of photoelectrons incident on the anode.
