Abstract

The MICE experiment intends to assess the feasibility of a Neutrino Factory and a Muon Collider and is based on the muon cooling technique: the muons pass through a series of absorbers decreasing their momentum while maintaining the beam size and reducing the emittance. At the end of the cooling section a detector able to distinguish single particles is required and is based on a KLOE-like front layer followed by fully active plastic scintillators, a calorimeter which in fact acts also as a tracker: the Electron Muon Ranger (EMR). The EMR detector consists of 50 planes organized in a x-y way, each one containing 59 scintillator bars with a triangular cross section. Each bar is readout by a single WLS fiber, inserted and glued in the bar hole, and connected to a 64 channel photomultiplier. On the other side of the bars, the fiber is connected to a single channel photomultiplier (one per plane) for the calibration and charge measurements. This paper presents the frontend and readout electronics of EMR which is based on VLSI ASICs and digital sampling to cope with the MICE rate. The analog info is provided by the single channel PMT whose signal is digitized by a VME waveform digitizer. The paper also describes the tests of the final electronics with the EMR prototype and of the first five long triangular bars at the CERN PS.
