- Summary
- The muon collider requires intense, cooled muon bunches to reach the required luminosity. Due to the limited life-time of the muon, the cooling process must take place very rapidly. Ionization cooling seems to be our only option, given the large emittances of the muon beam from pion decay. However, this ionization cooling method has been found quite difficult to implement in practice. We describe a scheme based on the use of liquid hydrogen absorbers fol-lowed by r.f. cavities (�pillbox� or �open iris� type), em-bedded in a transport lattice based on high field solenoids. These solenoidal fields are reversed periodically in order to suppress the growth of the canonical angular momentum. This channel has been simulated in detail with independent codes, featuring conventional tracking in e.m. fields and de-tailed simulation of multiple scattering and straggling in the the absorbers and windows. These calculations show that the 15 Tesla lattice cools in 6-Dphase space by a factor ≈ 2 over a distance of 20 m.
