Abstract

Dead time in detectors limits the capability of the detector to work at high counting rates. A correction for dead time can be used to estimate the particle flux from a measurement. A motivation for operating detectors at high counting rates is to get the best statistical accuracy. It is therefore also important to correct measurements for the loss of statistical accuracy that occurs when dead time is present. When the source of particles has a time dependent variation in intensity, the conventional dead time correction may not apply. A new dead time correction that applies in this case is presented.
