7
bq. The international Muon Ionization Cooling Experiment (MICE) will perform a systematic 
8
investigation of ionization cooling with muon beams of momentum between 140 and 240 MeV/c at the
9
Rutherford Appleton Laboratory ISIS facility.  The measurement of ionization cooling in MICE
10
relies on the selection of a pure sample of muons that traverse the experiment. To make this 
11
selection, the MICE Muon Beam is designed to deliver a beam of muons with less than ~ 1% 
12
contamination. To make the final muon selection, MICE employs a particle-identification (PID) system
13
upstream and downstream of the cooling cell. The PID system includes time-of-flight hodoscopes,
14
threshold-Cherenkov counters and calorimetry.  The upper limit for the pion contamination measured 
15
in this paper is f_{\pi} < 1.4% at 90% C.L., including systematic uncertainties.  Therefore, the
16
MICE Muon Beam is able to meet the stringent pion-contamination requirements of the study of
17
ionization cooling.
