Abstract:
The purpose is to make it possible to autonomously suppress a reduction in an electron beam without providing a means for supervising the electron beam intensity of a monitor or the like. An electron gun, provided with: a heater ( 12 ) in which one terminal serves as a heater terminal (H) and the other terminal serves as a shared terminal (HK), and in which a low-voltage power supply ( 21 ) is connected between the terminals, the heater ( 12 ) generating heat due to a current being supplied from the low-voltage power supply ( 21 ); and a cathode electrode ( 11 ) connected to the shared terminal (HK) and heated by the heater ( 12 ) to discharge thermal electrons. A cathode current (Ik) due to the thermal electrons discharged from the cathode electrode ( 11 ), and a current (Ih) due to the low-voltage power supply, flow in opposite directions through the heater ( 12 ).

Claim (Index 1):
An electron gun comprising:\n a heater, including one terminal as a heater terminal and another terminal as a shared terminal, to generate heat by current supply from a low-voltage power supply being connected between the terminals; and a cathode electrode, connected to the shared terminal, to form thermal electrons by being heated by the heater; wherein a cathode current generated by thermal electrons formed by the cathode electrode and a current generated by the low-voltage power supply flow through the heater in opposite directions.
