Abstract
A double-ended thyratron is provided which has, at each end, three grids between a cathode and adjacent voltage withstanding gap, the final grid being connected to its associated cathode. In a circuit arrangement including the thyratron, the first grid adjacent a cathode at each end is connected to a source of current bias and the intermediate grids at each end are connected to mutually isolated trigger signal sources.
Claims9
A double-ended thyratron having, at each end, a set of at least three grids between a cathode and means for providing at least one voltage withstanding gap.
A double-ended thyratron comprising, in combination:
- an envelope having a pair of cathodes disposed in spaced apart relation therewithin;
- and
- a first set of at least three grids adjacent one of said cathodes and a second set of at least three grids adjacent the other of said cathodes, the grids of each set being disposed in serially spaced fashion with the final grids of the two sets being disposed in remotely spaced, opposing relation and there being means providing at least one voltage withstanding gap between said first and second sets of grids, each set being exclusive of said means and comprising a first grid disposed closest to the associated cathode and adapted to receive an electrical potential independently of the remainder of the grids of that set whereby independently to receive a current bias, an intermediary grid between such first grid and the final grid of that set and adapted to receive an electrical potential independently of the remainder of the grids of that set whereby independently to receive a trigger pulse, and said final grid which is electrically connected to its associated cathode.
