A simple and versatile data acquisition system for software coincidence and pulse-height discrimination in 4πβ-γ coincidence experiments

► A simple but versatile data acquisition system for software coincidence experiments is described. ► Two ADCs were triggered simultaneously by the OR pulses from both discriminators. ► Paired digital signals for each sampling were sent to buffer memories connected to PC with a FIFO. ► Signal processing including pulse-height analyses was performed using MS-Excel. ► The usefulness of this system was demonstrated for measurements of 60Co, 134Cs and 152Eu.
