	Ionization cooling is essential to the Neutrino Factory in order to decrease the large emittance of the tertiary muon beam. Strong focusing and a large RF gradient in the cooling channel are required for efficient cooling; however, the presence of a strong magnetic field inside the RF cavities limits their performance by lowering the breakdown limit. In order to mitigate this problem a new lattice configuration, the Bucked Coils, is proposed: two solenoidal coils of different radius and opposite polarities are placed along the channel at the same z-positions. The Bucked Coils lower the magnetic field in the RF cavities while also providing strong focusing. This paper presents the results of the beam dynamics simulations in the new lattice, using the G4MICE code. The comparison of the achieved cooling performance and transmission between the currently proposed Neutrino Factory baseline lattice (FSIIA) and the new configuration is provided in detail.

	Funding: Science and Technology Facilities Council The international Muon Ionisation Cooling Experiment (MICE) is designed to provide a proof of principle of ionisation cooling to reduce the muon beam phase space at a future Neutrino Factory and Muon Collider. The MICE Muon Beam is generated by the decay of pions produced by dipping a cylindrical titanium target into the proton beam of the 800 MeV ISIS synchrotron at the Rutherford Appleton Laboratory, U.K. Studies of the particle rate in the MICE Muon Beamline and its relationship to induced beam loss in ISIS are presented, using data taken in Summer 2010. Using time-of-flight to perform particle identification estimates of muon rates are presented and related to induced beam loss.
