Hybrid Methods for Simulation of Muon Ionization Cooling Channels
AbstractCOSY Infinity is an arbitrary-order beam dynamics simulation
and analysis code. It uses high-order transfer maps
of combinations of particle optical elements of arbitrary
field configurations. New features have been developed and
implemented in COSY to follow charged particles through
matter. To study in detail the properties of muons passing
through a material, the transfer map approach alone is not
sufficient. The interplay of beam optics and atomic processes
must be studied by a hybrid transfer map–Monte Carlo approach
in which transfer map methods describe the average
behavior of the particles including energy loss, and Monte
Carlo methods are used to provide small corrections to the
predictions of the transfer map, accounting for the stochastic
nature of scattering and straggling of particles. This way the
vast majority of the dynamics is represented by fast application
of the high-order transfer map of an entire element
and accumulated stochastic effects. The gains in speed simplify
the optimization of muon cooling channels which are
usually very computationally demanding. Progress on the
development of the required algorithms is reported.
