Description
Coincidence electronics and pulse height analyzers stand as pivotal techniques in radiation detection
systems. The development of FPGA-based nuclear electronics has garnered attention due to their
programmability, simplicity, testability, compact size, and low power consumption. This technology is
increasingly favored worldwide for nuclear electronic systems over traditional analog counterparts. This
study presents advancements in coincidence electronics and a Pulse Height Analyzer (PHA) utilizing
commercial FPGA-based (Field-Programmable Gate Array) hardware for radiation scintillation
detectors. The hardware, based on a cost-effective NI myRIO device, integrates a Field-Programmable
Gate Array (FPGA), ARM Cortex-A9 processor, analog input (AI), digital input and output (DIO), and
USB/wireless connectivity with a host computer. LabVIEW codes, developed on the LabVIEWTM
platform, are implemented in NI myRIO hardware for seamless integration and computer interface. The
FPGA-based coincidence electronics performance is assessed through an experimental setup for the
gamma-gamma angular distribution of a Na-22 radioisotope source. Similarly, the FPGA-based PHA
undergoes testing with a NaI(Tl) detector, with a subsequent comparison of energy resolution against a
commercial EASY-MCA 2K from AMETEK Inc.
