Three data acquisition schemes for two-particle coincidence experiments with a continuous
source are discussed. The single-start/single-stop technique, implemented with a time-to-
pulse-height converter, results in a complicated spectrum and breaks down severely at high
count rates. The single-start/multiple-stop setup, based on a time-to-digital converter and the
first choice in today's similar coincidence experiments, performs significantly better at high
count rates, but its performance is still hampered if the time-of-flight range is large, and the …
