Ejm. Wallerbos et Je. Hoogenboom, EXPERIMENTAL INVESTIGATION OF THE COUNT-LOSS EFFECT DUE TO THE TIME-INTERVAL BETWEEN COUNTING-GATES IN THE FEYNMAN-ALPHA METHOD, Annals of nuclear energy, 25(4-5), 1998, pp. 203-208
Yamane and Hayashi derived a new formula for the variance-to-mean rati
o that takes the channel advance time of a multi-channel scaler into a
ccount. If the channel advance time is much smaller than the channel w
idth (as in practice), then its effect can be numerically shown to be
negligible. It might be for this reason that experimental results that
validate the new formula have never been published. However, by intro
ducing an artificial long channel advance time equal to the width of o
ne channel, the effect becomes significant and can be demonstrated exp
erimentally. With these experimental results, the new formula could be
validated. (C) 1998 Elsevier Science Ltd.
