In this work we report on a compact electronic readout system for position-sensitive photomultipliers (PSPMT) that are characterized by a large number of channels in a very small space, typically 64 over a 2" × 2" area. The proposed system allows the reading of all individual channel from a PSPMT, that is useful to fully exploit the information that can be acquired by this kind of system. The readout is controlled by an FPGA that collects the digitalized data from all the channels and send to a remote computer the events that are inside a configurable energy range. An electronic characterization of the readout is proposed, showing very low noise level and very good efficiency up to 20 thousand events per second. The proposed readout can be used for nuclear imaging application like SPECT and PET to improve spatial and energy resolution.

Abstract

In this work we report on a compact electronic readout system for position-sensitive photomultipliers (PSPMT) that are characterized by a large number of channels in a very small space, typically 64 over a 2" × 2" area. The proposed system allows the reading of all individual channel from a PSPMT, that is useful to fully exploit the information that can be acquired by this kind of system. The readout is controlled by an FPGA that collects the digitalized data from all the channels and send to a remote computer the events that are inside a configurable energy range. An electronic characterization of the readout is proposed, showing very low noise level and very good efficiency up to 20 thousand events per second. The proposed readout can be used for nuclear imaging application like SPECT and PET to improve spatial and energy resolution.
