A LYSO calorimeter for the SuperB factory

Abstract

The SuperB project is an asymmetric e^+e^− accelerator of 10^(36) cm^(−2) s^(−1) design luminosity, capable of collecting a data sample of 50–75 ab^(−1) in five years running. The SuperB electromagnetic calorimeter (EMC) provides energy and direction measurement of photons and electrons, and is used for identification of electrons versus other charged particles. In particular we present its design, geometry study and related simulations, as well as R&D on LYSO crystals and developments on readout electronics. A matrix of 25 crystals has been tested at the Beam Test Facility of Frascati (BTF) in May 2011 at energies between 200 MeV and 500 MeV. Results from this test are presented.
