    Since single-photon pulses of photomultiplier tubes (PMTs) have statistically fluctuating amplitude, constant-fraction trigger circuits (CFTs) are normally employed for accurate timing. However, with the subnanosecond signals of microchannel-plate types (MCPs) nonideal CFT behavior is observed....
