HIGH-FREQUENCY BUNCHING AND φ-δE ROTATION FOR A MUON SOURCE

A scenario for capture, bunching and rf rotation of µs from a proton source is presented. It consists of a drift section, a variable frequency ~300→180 MHz bunching section, followed by a fixed or variable frequency (~180 MHz) φ-δE rotation section. In 1-D and 3-D simulations (SIMUCOOL and ICOOL), the overall capture performance of the system is similar to that of induction linac + buncher scenarios developed for the neutrino factory.[1] The total rf required for the system is quite modest. Optimization procedures are described.
