Abstract:

A resonant air-core transformer was evaluated theoretically and experimentally as a pulser for an electron beam gun. The analysis has resulted in a set of design parameters which has been used to design a lightweight approximately 100 kg pulser for the generation of 150 kV, 40-A pulses of 30-microsec duration at 250 pps in 10-sec bursts. An experimental model has generated 150-kV, 2 to 5-A pulses of 10 to 14-microsec duration at 20 pps in operation limited by the available power supply. Experimental results have been in sufficient agreement with the theory to provide a high level of confidence in the full scale design. The efficiency predicted in the simplified case of decoupled losses varies from 42 percent with resistive charging to 56 percent by reactive charging methods. In general the dc-to-beam efficiency improves as the loading is increased and may approach approximately 60 percent in view of the coupling which realistically exists between loss elements.
