The SuperB muon detector, status and perspectives

The superB project foresees the construction of a high intensity super-flavor factory at the Cabibbo Lab, in Tor Vergata (near Rome). The experiment, based on a high intensity asymmetric electron-positron collider, and on the related detector, is expected to reach a very high luminosity: 2 × 1036 cm-2s-1, that will allow the high statistic study of rare decays and, possibly, will show evidences of new physics. The Muon Detector plays the fundamental role of identifying (mainly) muons tracks, present in many important decays. In order to cope with the very high particle flux, the detector must provide a very fast response and has to be very robust with respect to radiation damage and aging effects. The adopted technique exploits extruded plastic scintillators as active material, WLS fibers for the light collection and Silicon Photon Multipliers (SiPM) as photo-detectors In this manuscript, a complete description of the designed Muon detector and of all the related studies will be presented. In particular, we will focus on the results of a beam tests performed at Fermilab on a large scale prototype and on radiation tests of the most sensitive parts of the detector.
