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 5):
A high-frequency circuit system comprising:\n an electron tube according to  claim 3 ; and a power supply to supply electric power to the electron tube.
