Description

The He-3 high-pressure gas scintillation neutron detector commercially available as LND 800, has been compated to a Li-6 glass scintillator type NE 912. (n,γ) pulse height discrimination capabilities and neutron detection efficiencies have been determined. The objective of these measurements was to try to improve the Kiel Fast-Chopper TOF detector system by using a gasscintillator, which could cover the neutron beam geometry and by which gamma ray background contributions could be reduced. The time response always meets the requirements of a chopper experiment, but the neutron detection efficiency of the Li-6 glasses now used had to be maintained. (orig./HP)

Abstract (German)

Am Kieler Fast-Chopper wurden vergleichende Messungen zwischen einem Hochdruck-He-3-Gasszintillator (LND 800) und mit einem Li-6-Szintillatorglas NE 912 durchgefuehrt. Die Moeglichkeiten der (n,γ)-Impulshoehendiskriminierung, die Neutronenansprechwahrscheinlichkeiten und das Untergrund-zu-Signalverhaeltnis wurden untersucht. Es sollte festgestellt werden, ob mit Hilfe von He-3-Gasszintillatoren eine Verbesserung der Detektorbank des Choppers bezueglich Intensitaet und Verringerung des Untergrundes erzielbar sein wuerde.
