Abstract content
4
The Muon Ionisation Cooling Experiment (MICE) will demonstrate
5
ionisation cooling, an essential technology for a
6
Neutrino Factory and/or Muon Collider, by measuring a 10% reduction in
7
emittance of a muon beam. A realistic
8
demonstration requires beams closely resembling those expected at the
9
front-end of a Neutrino Factory, i.e. with large
10
transverse emittance and momentum spreads. The MICE muon beam line at
11
ISIS, RAL, was built to provide beams of
12
different momenta and emittance so that the performance of the cooling
13
channel can be fully explored.
14
During the initial stage of MICE, a novel technique based on
15
time-of-flight counters was used to establish that the beam
16
emittances are in the range 0.7--2.8 mm-rad, with central momenta from
17
170--280 MeV/c, and momentum spreads of about
18
20 MeV/c. These beams will be increased by means of scattering from
19
high-Z material in the next stage of MICE and
20
measured using magnetic spectrometers. Finally, low-Z absorbers such as
21
liquid hydrogen and LiH will be used to reduce
22
the emittance of the beam. The physics program of this step of MICE will
23
be discussed, including all stages necessary for a
24
first demonstration of ionisation cooling.
