A conceptual design of a high-pass-number Recirculating Linear Accelerator (RLA) for muons is presented. The scheme involves three superconducting linacs (201 MHz): a single pass linear Pre-accelerator followed by a pair multi-pass (4.5-pass) ‘Dogbone’ RLAs. Acceleration starts after ionization cooling at 220 MeV/c and proceeds to 12.6 GeV. The Pre-accelerator captures a large muon phase space and accelerates muons to relativistic energies, while adiabatically decreasing the phase-space volume, so that effective acceleration in the RLA is possible. The RLA further compresses and shapes up the longitudinal and transverse phase-spaces, while increasing the energy. Appropriate choice of multi-pass linac optics based on FODO focusing assures large number of passes in the RLA. The proposed ‘Dogbone’ configuration facilitates simultaneous acceleration of both μ± species through the requirement of mirror symmetric optics of the return ‘droplet’ arcs. Finally, presented end-to-end simulation validates the efficiency and acceptance of the accelerator system. [ABSTRACT FROM AUTHOR] |
