Abstract
The causes of an increase in the ТГИ 1-1000/25 thyratron jitter from 5 to ∼30 ns in pumping sources of metal-vapor lasers (MVLs) upon changes in the excitation-pulse repetition frequency from 700 Hz to ∼10 kHz are analyzed. It is shown that to provide the thyratron operation with an instability of the gridcathode gap breakdown of ∼1 ns, a hydrogen generator, and a device that forms an igniting pulse at the thyratron grid must be connected to stabilized dc power-supply units. Engineering solutions are proposed that allow control of the anode-current delay time at a thyratron jitter of ∼1 ns.
