The muon ionization cooling experiment(MICE) is a strategic R&D project
2
intending to demonstrate the only practical solution to prepare high brilliance
3
beams necessary for a neutrino factory or muon colliders.  MICE is under
4
development at the Rutherford Appleton Laboratory (UK). It comprises a dedicated
5
beam line to generate a range of input emittance and momentum, with
6
time-of-flight and Cherenkov detectors to ensure a pure muon beam. The emittance
7
of the incoming beam is measured in the upstream magnetic spectrometer with a
8
sci-fiber tracker. A cooling cell will then follow, alternating energy loss in
9
Li-H absorbers and RF acceleration. A second spectrometer identical to the first
10
and a second muon identification system measure the outgoing emittance. In the
11
2010-11 run the beam and most detectors have been fully commissioned and a first
12
measurement of the emittance of a beam with particle physics (time-of-flight)
13
detectors has been performed. The analysis of these data should be completed by
14
the time of the Conference. The next steps of more precise measurements, of
15
emittance and emittance reduction (cooling), that will follow in 2012 and later,
16
will also be outlined.
