Timing and Voltage Control of Magnetic Modulators on ETA II
Abstract
The Experimental Test Accelerator II is a high-average-power, high-repetition- rate linear induction accelerator at Lawrence Livermore National Laboratory. Magnetic pulse compressors are used in the power conditioning chains that produce pulses used to accelerate the electron beam. Stable operation of each power-conditioning chain is essential to overall accelerator performance. Variations in voltage or timing ("jitter") of pulses driving the induction cells can cause unacceptable variations in electron-beam energy. This paper reviews techniques developed and implemented to regulate voltage and to control sources of timing jitter. These techniques have demonstrated subnanosecond jitter and 0.1% pulse-to-pulse voltage regulation of the accelerator drive pulses.
