Numerical Study of Collective Effects for Muon Beams
The study of Muon beam optics is crucial for future Neutrino Factory and Muon Collider facilities. At present, the GEANT4-based simulation tools for Muon beam tracking such as G4beamline and G4MICE only do single particle tracking without collective effects taken into account. However, it is known that collective interaction such as space charge and wakefields for muons (in matter or vacuum) are not ignorable. As the first step, space charge computation is implemented into muon tracking. The basic algorithm is particle-to-particle interaction through retarded electro-magnetic field. The momentum impulse due to collective effects is applied to every particle at each collective step, and the G4beamline main code is used for tracking. Comparisons to LANL Parmela are illustrated and analyzed. Optimizations of the algorithm are also underway to gain less computing time and more accuracy. Moreover, the idea of enhancing ionization cooling efficiency by utilizing the collective effect due to the polarized charges in matter appears to be possible, and preliminary estimates have been made.
