Towards a new generation of solid total-energy detectors for neutron-capture time-of-flight experiments with intense neutron beams

J. Balibrea-Correa, V. Babiano-Suarez, J. Lerendegui-Marco, C. Domingo-Pardo et autres

Challenging neutron-capture cross-section measurements of small cross sections and samples with a very limited number of atoms require high-flux time-of-flight facilities. In turn, such facilities need innovative detection setups that are fast, have low sensitivity to neutrons, can quickly recover from the …
