Neutron capture measurements with high efficiency detectors and the Pulse Height Weighting Technique

Neutron capture cross section measurements in time-of-flight facilities are usually performed by detecting the prompt γ-rays emitted reactions. One of difficulties to be addressed these is that may change with neutron energy, and therefore also detection efficiency. To deal this situation, many use so called Total Energy Detection (TED) technique, combination Pulse Height Weighting Technique (PHWT). With it, it sought efficiency depends only on total energy γ-ray cascade, which does not vary much energy. This technique was developed 1960s has been used experiments date. requirements detectors have a low meant PHWT experimental setups efficiencies. However, condition fulfilled system as whole. The main goal work show possible measure high uses PHWT, how analyze measured data.
