| Popis: | Frequency characteristics of a subnanosecond plasma switch based on a combination of an open discharge or a discharge in a hollow cathode and a capillary discharge removed from the internal cavity of the plasma cathode are presented. It is shown that in the presence of an external screen that provides a capacitive discharge and hence, exclusion of the period of weak electron multiplication in the capillary from the delay mechanism of the discharge development, a high pulse repetition frequency is reached for different designs of the plasma cathode and the capillary section. It is demonstrated that at the voltage U = 30 kV, the pulse repetition frequency f = 100 kHz is reached for the capillary with round cross section at pHe ≤ 2.6 Torr and for the capillary with rectangular cross section at pHe ≤ 3.05 Torr. |
