TOFHIR2

We thank the MTD sensor team for providing the SiPMs and sensor modules used in the measurements and more generally the MTD project for all the support provided to the TOFHIR2 development. We also thank the CMS collaboration for creating the conditions that made this work possible. We thank the Microelectronics Group at CERN for all the support and advice in the development of TOFHIR2, as well as for making available the radiation tolerant bandgap block and the TMRG tool. We thank Federico Faccio, Giulio Borghello and André David for helping in the preparation of the radiation tests. In particular we are thankful to Federico Faccio for the extrapolation of the heavy-ion SEE data to the LHC environment presented in this paper. We also thank the coordinators of the CERN X-ray irradiation facility and of the Heavy Ion Facility (HIF) in Louvain-la-Neuve for making available these facilities and for the help provided.
