Abstract : The report concerns a feasibility study of electromechanical pulsers for the production of short duration, high power pulses with a low duty cycle. The pulse repetition rate is 0.200 pps. The output pulses are 40 kV, 1kA into a 40 ohm resistive load, with pulse duration between 20 and 40 us and with rise and fall times of 3 us or less. Several different approaches have been considered in an attempt to meet the requirements, including variable capacitance, variable reluctance, piezoelectric and electromagnetic generators with and without cryogenic fields. It was found that it is feasible to use an electromechanical pulser with some recommended switching schemes to meet the required pulse shape. Without switching, rise times approximately 13 us and fall times approximately 10 us are feasible. For some applications, a major advantage of an electromechanical pulser over conventional pulse methods is that high repetition rate bursts for short periods of time can be obtained.
