“…Each FEB integrates two low-noise ASICs for the readout of 192 channels, pulse amplification and shaping, performing also sequentially analog-to-digital conversion and data serialization and transmission to the off-detector data acquisition system [2]. Previous studies in the 7 T magnet facility at EPFL have demonstrated the mutual electromagnetic interference mechanisms and the integration feasibility of the ClearPEM front-end electronics and the MR system components [3].…”

a b s t r a c tIn the present work we intend to assess the readout feasibility of Avalanche Photodiode (APD) detectors via long signal lines for the development of a combined small-animal PET-MR prototype based on the ClearPEM technology. The detection performance of a LYSO-APD module was evaluated reading out the APD charge signals to the front-end ASIC via an 80 mm length flexible flat-cable (FFC). Experimental results showed a time resolution of 5.06 ns for the detector module in double-readout mode, with a nonsignificant degradation of 8.4% with the introduction of the FFC. The energy resolution of the system was not degradated by the FFC.
