Description
A high power, long pulse modulator aimed at application to International Linear Collider (ILC) is being developed. The target parameters are: 120 kV (±0.5%), 140 A, 1.7 ms, and 5 pps, with consideration on compactness, reliability, and cost control. A solid state, chopper controlled pulsed power generator using Marx-topology has been proposed.
This paper concentrates on the switching management and voltage-adding performance. The whole system is made of 20 units, each of them consists of 4 Marx-circuit boards and is designed for generating an output of 6.4 kV. The key technical issues here are the high-frequency chopping for droop compensation and the phase shift for ripple cancellation. The trade-off treatment between performance and efficiency and that between compactness and circuit cooling have been carried out by optimized design.
