TLDR
Relativistic klystron technology is used to extract 290 MW of peak power from an induction linac beam, and to power a short 11.4-GHz high-gradient accelerator to measure rf phase stability, field emission, and the momentum spectrum of an accelerated electron beam.Abstract:Â
We have used relativistic klystron technology to extract 290 MW of peak power at 11.4 GHz from an induction linac beam, and to power a short 11.4-GHz high-gradient accelerator. We have measured rf phase stability, field emission, and the momentum spectrum of an accelerated electron beam. An average accelerating gradient of 84 MV/m has been achieved with 80 MW of relativistic klystron power.read more

Anomalous electron loading in SLAC 5045 klystron and relativistic klystron input cavities
TL;DR: In this article, it was shown that after the onset of the RF drive pulse, the input cavity absorbs a portion of the incident RF drive that would otherwise be reflected from the not-beam-loaded cavity.
