Abstract
The Mu2e collaboration has developed a digitizer board that samples up to 20 differential signals with a frequency of 200 MHz, 12 bits of resolution, and dynamic range 0 - 2V. The digitizer has been qualified to operate in the hostile environment of Mu2E. The qualification levels are Total Ionizing Dose of 12 Krad and Neutron fluence of ∼ 1 0 11 1 MeVn eq /cm 2 , 1 T magnetic field, level of vacuum of 10 −4 Torr. The digitizer has aroused considerable commercial interest, as there are currently no digitizers with similar characteristics on the market. The original Mu2e board can’t be used as is and requires both hardware and firmware changes before entering the market. INFN funded a technology transfer project called HAMLET to support this new design. Additionally, HAMLET collaboration developed also a demonstration application based on an array of SiPM coupled to a scintillating crystal and connected to the digitizer. The demonstrator constitutes a complete and scalable, radiation qualified hardware platform, that can be used in hostile environments.
