Real-time elimination of dead time and afterpulsing in counting systems

A data taking scheme is described in which two photomultipliers record photons from a light source. It is shown that if the chain of recorded events is chosen to alternate between the two detectors, first-order effects of dead time and afterpulsing present in the two individual detectors are eliminated. This alternating scheme results in the detection efficiency being halved.
