CONTROL DEVICE AND CONTROL METHOD FOR ELECTRON EMISSION DEVICE FOR X-RAY GENERATION

WIPO Patent Application WO/2023/095940

A1

The present invention relates to a device of controlling an electron emission device generating X-rays, the device comprising: an electron emission device including at least one of at least one cathode electrode, an anode electrode paired with the cathode electrode, and a gate electrode for controlling a current flowing through the anode electrode; a cathode current detection part for detecting a current flowing through the cathode electrode of the electrode emission device; a reference voltage generation part for generating a reference voltage; and a gate voltage control part which receives the reference voltage and a detection voltage of the cathode current detection part, determines a gate voltage for controlling the electron emission device so that the detection voltage of the cathode current detection part becomes equal to the reference voltage, and applies the determined gate voltage to the gate electrode of the electron emission device.
