	The production process of pions which then decay into muons, yields a muon beam with large transverse and longitudinal emittances. Such beam requires phase space manipulation to reduce the total 6D emittance before it could go through any acceleration stage. The design of the muon beam manipulation is based on Neutrino Factory front end design. In this study we report on a multi objective - multivariable global optimization of the front end using parallel genetic algorithm. The parallel optimization algorithm and the optimization strategy will be discussed and the optimized results will be presented as well.

TUPME019	Design and Simulation of a High Field - low energy Muon Ionization Cooling Channel	1386
	H. K. Sayed, J.S. Berg, R.B. Palmer, D. Stratakis BNL, Upton, Long Island, New York, USA
	Muon beams are generated with inherited large transverse and longitudinal emittances. In order to achieve low emittance within the short lifetime of the muons, the only feasible cooling scheme is the ionization cooling. In this study we present a design and simulation of a novel ionization cooling channel. The channel operates at a very strong magnetic fields of 25-30 T with low muon beam energy starting from 66 MeV and decreasing gradually. We study the beam dynamics of such low energy beam in high field region inside and between cooling stages. Key design parameters will be presented and in addition the performance and channel requirements of RF cavities and high field magnets will be presented.

	Funding: Work supported by Brookhaven Science Associates, LC under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy. We describe a muon capture section to manipulate the longitudinal and transverse phase-space so that to collect efficiently a muon beam produced from an intense proton source target. We show that this can be achieved by using a set of properly tuned rf cavities that captures the beam into string of bunches and aligns them into nearly equal central energies, and a solenoidal chicane that filters high momentum particles, followed by a proton absorber that reduces the energy of all particles. This work elucidates the key parameters that are needed for successful muon capture, such as the required rf frequencies, rf gradients and focusing field. We discuss the sensitivity in performance against the number of different rf frequencies and accelerating rf gradient.
