FPGA-Based random radioactive source signal generator

Abstract

Signal Generators are used in many scientific research fields. It is also widely used in nuclear electronics. Being able to emulate the signals generated by radioactive sources in liquid/plastic scintillators is very important for the safety of research. These signals are fast at the ns-μs level and have a random nature. Therefore, special methods are required to generate them because of this randomness. In this study, an FPGA-based signal generator design that can generate a radioactive source signal of random amplitude at random times is presented. The system was able to successfully emulate the signal of a real radioactive source.
