Abstract:
This paper describes the first step in the development of a digital platform dedicated to primary radionuclide measurements. In order to validate the implementation of an on-line processing based on extendable dead-times, a FPGA-based digital system has been programmed for liquid scintillation counting. After a description of the hardware, TDCR (Triple to Double Coincidence Ratio) measurements are presented. Comparisons of activity measurements with the classical system operating at LNHB are used to validate the new system; coincidence counting differences observed when increasing the resolving time in the digital platform are discussed.
