PATARA II: A 64-channel solid-state Neutron Detector readout system with integrated analog and digital processing for the SNS

The High Efficiency Neutron Detector Array (HENDA) project at the Spallation Neutron Source(SNS), Oak Ridge Tennessee, has driven the need for state of the art radiation detector readout electronics. Readout electronics of this class must support multi-channel inputs while providing a high level of integration and precision. The Patara II ASIC targets this need by integrating a charge sensitive front end followed by analog and digital signal processingthat supports the connectivity of 64 detectors. A monolithic biasing system and digital programmability was integrated in order to reduce the amount of required external components on the end system motherboard.
