Abstract

In this study, the calibration process of the EXOGAM2 conventional gamma detector system with the newly developed digital electronic device, namely NUMEXO2, will be presented. This experimental study was performed at the GANIL (Grand Accélérateur National d'Ions Lourds) nuclear research center in France. The energy calibration of the EXOGAM2 detector system with the newly developed NUMEXO2 digital electronic device was conducted using both low and high gamma energy levels of a 152Eu radioactive source. This calibration was carried out for two EXOGAM2 detectors, and the energy resolution of each crystal in the EXOGAM2 system was determined.
The energy resolution of each crystal was found to be reasonable energy resolution values of the EXOGAM2 detectors. Therefore, the use of the digital electronic device NUMEXO2 did not affect the energy resolution of the detectors, but it did enable us to acquire data at a high counting rate.
