Abstract

Field-programmable gate array (FPGA) technology has been widely used in setting up triggering systems and DAQ systems for radiation detectors, because it has several advantages such as fast digital processing, compact, programmable and high stability. Since 2010, with we have developed FPGA-based trigger systems and FPGA-based DAQ systems used for radiation detectors. Triggering systems for cosmic ray measurements, readout electronic for environmental radiation monitor in air. We also developed nuclear electronic equipment such as spectrum analyzer MCA (Flash-ADC/FPGA based), the pulse generator, counters, readout electronic for multiple radiation sensors. In this paper, we present two experiments, on the cosmic-ray induced response on the NaI(Tl) detector and environmental radiation monitoring system. For those experiments, trigger system are built by FPGA-based technology.
