Abstract
The switching properties of a new gas-discharge sharpener that consists of “open” and “capillary” discharges serially connected in a bulk are studied. The switching times less than 1 ns have been attained in helium in a wide range of conditions, at times of discharge development delay higher than 600 ns with an initial pulse compression degree of about 103. An average power of about 10 kW has been implemented in the pulse train mode at a voltage of 20 kV and a pulse frequency of 44 kHz.
