	The dependence of the performance of the Front End of a Muon Collider/Neutrino Factory on the proton-beam bunch lengths of 0-20 ns is explored for beam kinetic energies of 3 and 8 GeV.

TUPBA11	TOWARDS A GLOBAL OPTIMIZATION OF THE MUON ACCELERATOR FRONT END	547

	The baseline design for the neutrino factory and muon collider front end consists of a five major components, namely the muon production target, decay channel, buncher, phase rotator, and the ionization cooling channel. Although each of the mentioned systems has a complex design which is optimized for the best performance with its own set of local objectives, the integration of all of them into one system requires a global optimization to insure the effectiveness of the local objectives and overall performance. This global optimization represents a highly constrained multi-objective optimization problem. The objectives aimed for are the number of muons captured into a stable bunches and their transverse and longitudinal emittances. These objectives are constrained by the momentum and dynamic acceptance of the subsequent acceleration systems in addition to the overall cost. A multi-objective global evolutionary algorithm is employed to address such a challenge. In this study a statement of optimization strategy is discussed along with preliminary results of the optimization.

THPHO11	Optimization of the Capture Section of a Staged Neutrino Factory	1325

	A proposed staged Neutrino Factory, producing lower muon intensity of 10²⁰ muons per year and 10^-14 GeV muon beam energy, initially requires target station for 1~MW proton beam power with a proton beam energy of 3~GeV, which could be upgraded to the full power of 4~MW at 8-GeV beam energy. The optimization of the initial Target Station and the following Decay Channel and Buncher/Phase Rotator are discussed.
