A simple mechanically operated subnanosecond rise-time generator for pulses up to 100 kV

A mechanically triggered generator capable of delivering pulses up to 100 kV with subnanosecond rise-times in a coaxial system is described and oscillograms of typical pulses obtained with this generator are given. The pulses are generated by switching a spark gap, but it has been found that the second sharpening gap which has been used in previous switches employing this technique is not necessary with this arrangement. The design and results of a resistance divider, used to attenuate these pulses, is included.
