The Electron-Muon Ranger (EMR) is a totally active scintillator detector (TASD) to be installed in the muon beam of the Muon Ionization Cooling Experiment (MICE) - the R&D project for the future neutrino factory. The EMR is made of 48 intersecting layers. Each layer consists of 59 triangular scintillator bars. Each bar incorporates a wave-length shifting (WLS) fiber that collects light emitted by the scintillator. At the faces of each bar the WLS fiber is coupled to a light guide that transfers light to a PMT. Scintillatior bars are read out at both sides, one side is connected to a single-channel PMT and the other - to the 64-channel PMT. The granularity of the detector allows us to identify tracks and measure particle ranges and shower shapes. The EMR will be installed at the very end of the MICE cooling channel and will stop and measure all outgoing particles. Currently it is being built at the University of Geneva and it is planned to install it in MICE by the end of 2012.
