Abstract
A pulse generator has been developed which has many potential applications. The pulse generator consists of a high-voltage modulator incorporating two stacked Field-Effect Transistor switches operating in a “push-pull” mode. A continuous 1 kV to 6 kV pulse train has been obtained with a prototype pulse generator over a frequency range from 1 Hz to 20 kHz. Pulse widths in the range from 250 ns to 1 s have been achieved with rise and fall times of 30 ns into a capacitive load of 26 pF. A 3 kHz, 5 kV version of this pulse generat,or has been installed and t,ested in the 300 keV injection line for t,he 500 MeV TRIUMF cyclotron. The circuit performance was evaluated with the aid of PSpice in t,he design stage and confirmed by measurement,s in the prototype. Results of measurements and simulations are presented.
