NUCL 205 Exp 5: Dead Time 1/3 2/14/2010 School of Nuclear Engineering Purdue University West Lafayette, IN 47907-1290 NUCL 205 Experiment 5: Dead Time 1 Objectives The objectives of this experiment are: 1. To investigate the affect of detector and/or system dead time on the number of counts recorded by a counting system 2. To investigate methods of correcting the recorded counting rate to determine the true counting rate; and 3. To investigate two methods of determining the dead time of a G-M detector. 2 Introduction The dead time, τ , can be defined as the minimum time required between pulses so that the counting system can distinguish, analyze, and count each pulse. All pulse-type electronic equipment has some dead time; the only difference being in the magnitude of the dead time and what happens when two pulses occur within this minimum period of time. In some cases, the equipment will be dead to all incoming pulses for some time, , after a pulse is accepted and the amplitude and analysis of the first pulse is unaffected. (Such equipment is called nonparalyzable.) In other systems, the equipment may be dead for a time, , after the interaction of any radiation with the detector.
