Descripción
Segmented double-scatter Compton camera systems have been widely used for imaging gamma sources. There are examples of the same technique applied for neutron source imaging, however, such devices tend to be bulky and require considerable supporting infra-structure. We will present a compact design that utilizes a segmented scintillator stack, SiPMs, NeuPix ASICs, and an FPGA-based readout system. This device is battery operated and will be hand-held portable because none of the components require high voltage to operate. Design features of the imager and preliminary results will be presented. Programmable flexibility inherent the NeuPix ASIC will be described, and performance data will also be presented. The relevance of this effort to LIDINE lies in applications requiring neutron scattering based calibrations of prototype dark matter detectors, imaging of background neutrons/gammas, and design of new experiments based on this technology.
