Abstract :
The efficiency of a mineral-oil-based scintillation detector, with 0.1% by weight of Gd within the walls of a modular substructure, was measured and calculated. From these measurements a detection efficiency of 28.6% can be deduced, for neutrons produced by a neutrino-proton reaction in the 56-t neutrino detector KARMEN, that neutrons from the inverse beta -decay reaction in KARMEN can be detected with high probability via the Gd(n, gamma ) reactions. A neutron efficiency of about 30% is thus possible, which means that high-efficiency neutrino detection is possible in KARMEN.<>
