Abstract:

Thyratrons are designed to operate in the low pd pressure times distance region of the Paschen characteristics of the gas order to achieve high-voltage operation. In hydrogen thyratrons the most widely used modulator device operating in this pressure region, reliable operation with a single high-voltage gap is limited to about 35 kilovolts. The minimum pressure and the interelectrode spacing are limited by the need to maintain adequate density for conduction of high current and effective cooling of the electrode particularly during commutation, and by field-emission breakdown. In order to obtain high-voltage operation, it is necessary to divide the voltage over many gaps by the addition of gradient grids. A design for iterative grids has been evolved that permits unlimited stacking to provide operation at any voltage level desired. Basic design considerations and the experimental procedure and facility are discussed. Author
