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.
Claims16
A vacuum tube for amplifier circuit, comprising:
- an incidence window portion configured to transmit signal light;
- a photoelectric conversion unit configured to convert the signal light transmitted through the incidence window portion into photoelectrons;
- an output unit configured to have an anode, on which the photoelectrons are incident, and output a signal corresponding to the incident photoelectrons;
- and
- a grid electrode configured to be disposed in a path of the photoelectrons from the photoelectric conversion unit to the anode and control an amount of the photoelectrons incident on the anode.
