A γ-Ray Detector of the INES Setup for Measuring Neutron Cross Sections

— A liquid-scintillator γ-ray detector has been investigated. The electronics, which consists of a preamplifier and a shaping amplifier of the detector signals, is described. A method for determining the start pulse for the time-of-flight technique has been developed based on the detection of several (three or more) γ rays from a neutron source in a narrow time interval. This method is insensitive to the timing instability of the sync pulse of the proton beam. The energy resolution of the γ-detector section is compared to the simulation results for the γ-ray detection. The potential of the γ detector for measuring cross sections for radiative neutron capture by a nucleus is shown.
