750 kV high-voltage pulse generator for the negative hydrogen ion injector in the Moscow meson factory's linear accelerator

A layout of the negative-polarity high-voltage pulse generator based on pulse transformer, modulator with the forming line, device for pulse leading and trailing edge formation and diode-condenser limiter at the pulse transformer output is developed. The generator differs from the earlier known ones in a possibility of back-discharge energy recuperation and decreased voltage on thyratrons of the device for pulse leading and trailing edge formation which allows one to eliminate repeated thyratron operations. To reduce pulsations of the output voltage and overvoltages in the pulse transformer an additional inductive-capacitive cell intended for pulse transformer coordination with the forming line and with the device for the pulse edge formation is installed at its input. Investigations into the operating modes of the generator and its elements at 10 Hz pulse frequency and 750 kV voltage are conducted which allows one to select the generator element parameters for operation at 100 Hz frequency. 4 refs.; 5 figs
