Abstract

A new 4π (LS) TDCR system was built at ENEA-INMRI. Three photomultiplier tubes, arranged in a planar 120° geometry around a spherical optical chamber, were directly linked to a CAEN Desktop Digitizer DT5720. This module, based on the Field Programmable Gate Array (FPGA) technology for real time Digital Pulse Processing (DPP), allowed to replace all the classical TDCR electronics by only one device. The activity of (3)H and (63)Ni standard sources were successfully measured by the new detector.

Keywords: Digital pulse processing; Low-energy pure beta emitters; TDCR counter.
