Abstract

The stability of the Dynamitron high voltage generator is influenced by several factors: 1) beam load changes, 2) changes in the power mains, 3) frequency components in d.c. anode power to the oscillator tubes, and 4) modulation due to a.c. heated filaments. A brief analysis based on experimentally obtained data and the reasons for stabilizing the generated voltage by means of a multi-loop feedback system are presented. Measurements made on a 3.0MeV accelerator show that terminal ripple is 1500 volts peak-to-peak and that the regulation from zero to six milliamperes of beam is less than ±1500 volts. Future improvements in the generator and regulating electronics design should result in reducing the ripple to 600 volts peak-to-peak and the regulation to ±600 volts.
