Testing radiation tolerance of SerDeses for the SuperB experiment

SuperB is a novel, high luminosity (10³⁶ cm^-2 s^-1), asymmetric e+e- collider to be built at the Cabibbo Laboratory, in the campus of the University of Rome Tor Vergata (Italy). A detector and its associated electronics (ETD) will be installed in this facility. High-speed serial links will be used for trigger and clock distribution and for data read-out. Given the high luminosity of the accelerator, the on-detector ends of the links will have to cope with the expected radiation levels. In this work, we present the results of irradiation tests on some off-the-shelf components candidate for the electrical part of the links. We tested both standalone SerDeses and FPGA-embedded ones. We irradiated the components with a 62-MeV proton beam at INFN Laboratori Nazionali del Sud (Catania, Italy) and with a Cobalt-60 γ-ray source at ENEA, La Casaccia (Rome, Italy).
