Mueller, J W

The classical Moon method (1937) for measuring dead times consists of measuring the count rates of two radioactive sources, in the first place, separately, and then together. Recently Baerg proposed an interesting modification to this method in which one of the sources is replaced by an oscillator. In the case where the time intervals between the superimposed pulses are determined uniquely by the random pulses of the source the accuracy required is attained in a period of time reduced by a factor of three in relation to the conventional method, in addition the result obtained no longer depends on the type of dead tiine (cumulative or noncu tive). It is demonstrated that this assumption is invalid and that in consequence modifications must be made to the simple formulas suggested by Baerg for determining the dead time. (FR)
