Harmonic fast kicker • Baseline kicking scheme moving forward: – Frequencies for kicker modes

Harmonic fast kicker • Baseline kicking scheme moving forward: – Frequencies for kicker modes settled, six odd harmonics of 86. 6 MHz – Needs to finalize other parameters such as kicking angle and aperture • Vacuum model concept in progress – Simplified one cavity 6 modes design – Size similar to Yulu’s ½ model cavity, with 1 additional tuner (5+1) – Asymmetric design: cavity needs to be optimized for minimal longitudinal R/Q • Compatible for UITF/LERF tests – Gun needs to operate at 136 MHz reprate
