Abstract
We report on the design and performance of the Digitizer ReAdout Controller (DIRAC) of the Mu2e electromagnetic calorimeter, which consists of a 670 CsI crystals matrix readout by SiPM. The 20-channels DIRAC performs 200 MHz sampling of the SiPM signals transmitted by the front-end electronics. Operation in the Mu2e hostile environment expected Total Ionizing Dose (TID) of 12 Krad and neutron fluence of 5x10 10 n/cm 2 @ 1 MeV eq (Si)/y, 1T magnetic field, level of vacuum of 10 -4 Torr has made the DIRAC design challenging. We describe design, specifications, architecture and results of the tests performed on the DIRAC prototypes.
