Pushing the Capture Limit of Thermionic Gun Linacs
Sadiq Setiniyaz, Alejandro Castilla, Julian McKenzie +4
Although accelerator technology has matured sufficiently, state-of-the-art X-ray linacs for radiotherapy and cargo-scanning capture merely 30-50% of the electrons from a thermionic…

Prediction of Beam Losses during Crab Cavity Quenches at the HL-LHC
Robert Apsimon, Graeme Burt, Amos Dexter +10
Studies of the crab cavities at KEKB revealed that the RF phase could shift by up to 50o within ~50 us during a quench; while the cavity voltage is still at approximately 75% of it…
