Description

Muon beams of low emittance provide the basis for the intense, well­ characterised, neutrino beams necessary to elucidate the physics of flavour at the Neutrino Factory and to provide lepton-­antilepton collisions up to several TeV at the Muon Collider. The international Muon Ionization Cooling Experiment (MICE) will demonstrate ionization cooling, the technique proposed to reduce the phase­-space volume of the muon beam at such facilities. In an ionization­ cooling channel, the muon beam traverses a material (the absorber) loosing energy, then replaced by reaccelerating RF cavities. The combined effect is to reduce the transverse emittance (transverse cooling). The rebaselined project will deliver a demonstration of ionization cooling by September 2017. In the revised configuration 1) a central lithium ­hydride absorber provides the main cooling effect 2) the magnetic lattice is two SC focus-coil modules 3) acceleration is provided by two 201 MHz single-­cavity modules. The phase space of the muons in and out of the cooling cell will be measured by two SC solenoidal spectrometers. All the SC magnets for the ionization-cooling demonstration are available at RAL and the first single­cavity prototype has been tested successfully in the MuCool Test Area at Fermilab. The design of the cooling demonstration experiment, a summary of the performance of each of its components and the cooling performanceof the revised configuration will be described.

additional information

This is an abstract aiming at a poster in the accelerator session complementing, together with another poster, a talk in the same session.

The three are submitted by the chair of the Speakers Bureau of the MICE collaboration as a coherent set of contributions. The Bureau will identify a member of the collaboration to present each accepted contribution.
