Characterization of a front-end electronics for the monitoring and control of hadrontherapy beams

摘要

An integrated 64-channel device for the read-out of parallel plate pixel and strip ionization detectors has been developed by the INFN and University of Torino. The detectors will be used for the monitoring and control of hadrontherapy beams. The ASIC has been designed in CMOS 0.8 μm technology and it is based on a current-to-frequency converter followed by a synchronous counter. In this paper, we present a detailed characterization of the device done with 113 chips.
