Abstract
A radiation tube that is used in a radiation source for radiography includes: an electron emitting unit that includes a cathode unit having an emitter electrode which emits electrons and a gate electrode; an anode unit that has an anode surface facing the cathode unit and collides with the electrons to generate radiation; a constant voltage supply unit that supplies a constant driving voltage to the gate electrode; and a vacuum tube that accommodates the constant voltage supply unit, the electron emitting unit, and the anode unit.
