Tests of a resonance detector spectrometer for electron-volt spectroscopy
Abstract
A resonance detector spectrometer at the KENS neutron source, using Ta-181, Sb-121, and Sm-149 absorbers and bismuth germanate (BGO), NaI and plastic scintillators was tested. In the process numerous background problems were solved, a time-focussing principle was discovered. The scattering from a number of materials was measured and results for bismuth and graphite were analyzed. Tests of cooled absorbers have indicated that resolution of 70 MeV is possible with Ta-181.
