A Neutrino Factory based on a muon storage ring is the ultimate tool for studies of neutrino oscillations, including possibly the discovery of leptonic CP violation. It is also the first step towards a muon collider. The muon ionization cooling experiment (MICE) is a strategic R&D project intending to demonstrate the only practical solution to prepare high brilliance beams necessary for a neutrino factory or muon colliders. MICE is under development at the Rutherford Appleton Laboratory (UK). The experiment is a single particle experiment and utilizes many detector techniques from high energy physics experiments. In order to monitor the purity of the beam and tag the arrival time of individual muons, a dual aerogel Cherenkov system and a plastic scintillator time-of-flight system is used. The phase-space vectors of the muons will be measured by two identical spectrometer systems (one before and one after the cooling apparatus) which employ a fiber tracker system, and electron and muon calorimeters are used to tag outgoing muons. In the 2010 run the beam and most detectors have been fully commissioned and a first measurement of the emittance of a beam with particle physics (time-of-flight) detectors has been performed. The latest particle identification system analyses and results will be discussed.
