ABSTRACT:
A gas discharge tube includes a first spacer, a second spacer, an anode support member, and an anode. The first spacer is arranged to contact the rear surface of the focusing electrode support member and the front surface of the anode, and the second spacer is arranged to contact the front surface of the anode support member and the rear surface of the anode. This arrangement clamps the anode between the first and second spacers to hold the anode securely between the rear surface of the focusing support member and the front surface of the anode support member, keeping the distance between the focusing electrode and the anode constant. This structure improves the service life and the operational stability of the gas discharge tube during continuous light emission over an extended period of time.
