Abstract
The performance of n-gamma pulse-shape discrimination for a liquid scintill ation detector has been investigated for gamma-ray count rates up to 50 kcp s. A method in which the ratio of the total to partial charge in the anode pulse is directly measured has shown much improved quality of the pulse-sha pe discrimination when pile-up events are rejected; it can discriminate neu tron events of 50 cps from gamma-ray events of 29 kcps. The method with sim ple pile-up rejection has the advantage that only general purpose electroni cs are required. (C) 1999 Elsevier Science B.V. All rights reserved.
