Description
The rectilinear cooling channel of a muon collider requires high-gradient normal-conducting RF cavities to enable ionization cooling, which is essential to achieve high luminosity. Reaching this performance demands bunches containing $\sim 10^{12}$ muons. At these intensities, beam-induced wakefields can cause significant beam loading, reducing the accelerating gradient and affecting beam stability.
This paper presents the conceptual RF design and analysis of beam-induced effects in copper cavities designed to meet the beam dynamics requirements of the muon cooling channel. Cavities are optimized and compared in terms of RF performance and power requirements. Wakefields and beam loading are analyzed, and a compensation strategy for beam loading is proposed.
