Performance characteristics of an induction linac magnetic pulse compression modulator at multi-kilohertz pulse repetition frequencies

摘要

The ETA-II linear induction accelerator utilizes four pulse power conditioning chains. Magnetic pulse compression modulators (MAG1-Ds) form the last state of each chain. The upgrading and characterizing of the power conditioning chain on a high-average-power test stand (HAPTS) is reported. On the HAPTS, the pulse-to-pulse amplitude stability has been improved to less than 0.7% (one sigma) and the random jitter to 3-5 about a systematic timing variation. A description is presented of the work to achieve the desired performance level of the MAG1-D to allow high average power operation of ETA-II.
