Abstract

The Karlsruhe 4n BaF2 Detector is composed of 42 crystals of 1.5 1 volume, shaped as hexagonal or pentagonal truncated pyramids, forming a spherical shell of 20 cm inner diameter and 15 cm thickness. Each crystal is covered by a thin reflector and viewed by a phototube, thus representing a complete gammaray detector. The energy resolution of the individual detector modules is 10- 11 % at 662 keV and 4 - 5% at 6.13 MeV gammaray energy, while the time resolution as measured with a 60Co source is 400 - 500 ps. The overall efficiency of the entire detector is about 100% for gamma-rays up to 10 MeV. Compared to 4n detectors with compa rable efficiency made from NaI (TI) as the Oak Ridge spin spectrometer or the Heidelberg crystal ball detector the present setup offers 5 times better time resolution at similar resolution in gamma-ray energy. The detector will be used for the accurate determination of neutron capture reactions in the neutron energy range from 3 to 200 keV primarily for astrophysical applications. The performance of the detector under experimental conditions is demonstrated in various test measurements on gold samples.
