Abstract : The muon ionization cooling experiment(MICE) is a strategic R&D p

roject intending to demonstrate the only practical solution to prepare high

brilliance beams necessary for a neutrino factory or muon colliders.  MICE i

s under development at the Rutherford Appleton Laboratory (UK). It comprises
5
 a dedicated beam line to generate a range of input emittance and momentum, 
6
with time-of-flight and Cherenkov detectors to ensure a pure muon beam. The 
7
emittance of the incoming beam is measured in the upstream magnetic spectrom
8
eter with a sci-fiber tracker. A cooling cell will then follow, alternating 
9
energy loss in Li-H absorbers and RF acceleration. A second spectrometer ide
10
ntical to the first and a second muon identification system measure the outg
11
oing emittance. In the 2010-11 run the beam and most detectors have been ful
12
ly commissioned and a first measurement of the emittance of a beam with part
13
icle physics (time-of-flight) detectors has been performed. The analysis of 
14
these data should be completed by the time of the Conference. The next steps
15
 of more precise measurements, of emittance and emittance reduction (cooling
16
), that will follow in 2012 and later, will also be outlined.
