Optical Detector with Integrated ADC for Digital Readout
Most nuclear physics experiments use PMTs coupled to scintillators, which require a readout using BNC cables, HV cables, HV suppliers, analog-to-digital converters (ADCs), and possibly additional modular electronics and mainframes for signal processing. These items tend to account for a significant amount of the cost per detector channel, which limits both the size of the experiment and the number of detector channels. A novel method for signal digitization is required to reduce these costs. This project will investigate the use of a CMOS solid-state photomultiplier (SSPM), integrated with an on-chip ADC, as a cost-effective method for digitizing the signal. ADC units will be developed from commercially available components, and feasibility will be demonstrated through spectroscopic measurements and cost analysis. Commercial Applications and other Benefits as described by the awardee: These devices may find use in a variety of experiments as a viable alternative to the traditional method for scintillator readout. Furthermore, a standardized design for an SSPM with integrated ADC could provide a functional platform for a myriad of low-cost, compact applications, including gamma-ray spectroscopy, flow cytometry, neutron detection, dosimetry, and nuclear imaging.
