Abstract
A heating apparatus includes a heater, an electron reflection plate, a filament arranged between the heater and the electron reflection plate, a heating power supply configured to supply an AC voltage between a first terminal and a second terminal of the filament to emit thermoelectrons from the filament, an acceleration power supply configured to supply an acceleration voltage between the filament and the heater, and a resistor arranged so as to form a path which connects the electron reflection plate and the heating power supply.
