Abstract
A thyratron has an auxiliary "keep-alive" electrode in the form of a surface element with at least one aperture therein. In a preferred embodiment, the auxiliary electrode is disposed adjacent the upper end of a heat shield surrounding the cathode of the thyratron and is preferably coplanar with the upper end of the heat shield. A baffle can also be provided between the auxiliary electrode and the cathode to enhance control of the thyratron's switching action.
Claims12
A thyratron comprising:
- an anode structure, a cathode structure and a heat shield, the heat shield disposed about the cathode structure and terminating in an upper end facing the anode structure;
- a control electrode disposed between the anode structure and the cathode structure;
- an auxiliary electrode adjacent the upper end of the heat shield, the auxiliary electrode comprising a surface element having at least one aperture therethrough;
- and
- said surface element of the auxiliary electrode being substantially coplanar with the upper end of the heat shield.
