Recent advances in magnetically driven induction linacs

This paper reports on increased interest in high-current, short-pulse electron beams for a wide variety of applications, including free-electron lasers, which has generated a demand for high-performance, high-reliability induction accelerators. Advances in this technology will be reviewed. Designing the drive pulse sources is particularly challenging because the sources must deliver multi-gigawatt pulses with rise times of a few nanoseconds and pulse lengths of a few tens of nanoseconds. Recent developments in all- solid-state nonlinear magnetic drivers will also be discussed
