Abstract

The results of investigations of converters ensuring correction of the shape and energy compression of high-voltage (∼200 kV) pulses with durations of several nanoseconds and the formation of pulses with subnanosecond rise times across a load of ∼50 Ω are described. The converters are assembled on the basis of forming and transmitting coaxial lines and a high-pressure nitrogen spark gap. Correcting devices are open-circuit strip-line stubs connected to different points of the transmitting or forming line. Depending on the stub connection point, a series or parallel discharge of the forming line and stub to the load is initiated after switching of the spark gap. As a result, the pulse may become either longer or shorter; in the latter case, its amplitude increases. The design of the stubs built into the insulating gap of the coaxial line does not increase the size of the device at all.
