The Muon Ionization Cooling Experiment (MICE) at the Rutherford Appleton Laboratory aims at demonstrating a ∼ 5% ionization cooling effect on a muon beam by its interaction with low-Z absorber materials followed by restoration of longitudinal momentum in RF cavities. The final configuration of MICE will add to the Step IV hardware a second Focus Coil module and two 201.25 MHz RF cavities to provide a 10.3 MV/m accelerating gradient. This requires an RF drive system and distribution network to deliver ∼2MW of power in 1 ms pulses at 1 Hz repetition rate to each cavity with correct RF phasing and diagnostics to determine the gradient and the muon transit phase. Progress towards the completion of the final configuration is described.

“…The particle identification should achieve a pion rejection factor -1 - between 10 and 100, so a pion contamination in the beam of ∼1% should reduce the misidentified pion contamination in the muon sample to less than 0.1%, required to achieve the physics goals. The pion contamination of the MICE Muon Beam was measured in dedicated data-taking runs in order to qualify the muon beam and to ensure that MICE can achieve its stated physics goals [21,22]. The paper is organised as follows: a brief description of the MICE experiment is included in section 2, the MICE Muon Beam is described briefly in section 3, the analysis method is described in section 4 and the results and systematic errors are given in section 5, followed by a brief conclusion (section 6).…”

Pion contamination in the MICE muon beam

A: The international Muon Ionization Cooling Experiment (MICE) will perform a systematic investigation of ionization cooling with muon beams of momentum between 140 and 240 MeV/c at the Rutherford Appleton Laboratory ISIS facility. The measurement of ionization cooling in MICE relies on the selection of a pure sample of muons that traverse the experiment. To make this selection, the MICE Muon Beam is designed to deliver a beam of muons with less than ∼1% contamination. To make the final muon selection, MICE employs a particle-identification (PID) system upstream and downstream of the cooling cell. The PID system includes time-of-flight hodoscopes, threshold-Cherenkov counters and calorimetry. The upper limit for the pion contamination measured in this paper is f π < 1.4% at 90% C.L., including systematic uncertainties. Therefore, the MICE Muon Beam is able to meet the stringent pion-contamination requirements of the study of ionization cooling.
