摘要

The ~(10)B based Jalousie detector is a replacement for ~3He counter tubes, which are nowadays less affordable for large area detectors due to the ~3He crisis. In this paper we investigate and verify the performance of the new ~(10)B based detector concept and its adoption for the POWTEX diffractometer, which is designed for the detection of thermal neutrons with predicted detection efficiencies of 75-50% for neutron energies of 10-100 meV, respectively. The predicted detection efficiency has been verified by absolute measurements using neutrons with a wavelength of 1.17 A (59 meV).
