Neutron-induced reaction studies at FIGARO using a spallation source
TL;DR: Fast Neutron-Induced Gamma-Ray Observer (FIGARO) as discussed by the authors is designed to study fast neutron-induced reactions that result in the emission of γ rays and neutrons.

TL;DR: In this article, a digital data acquisition system has been combined with a double Frisch gridded ionization chamber for use at both moderated and unmoderated neutron sources at the Los Alamos Neutron Science (LANSCE) facility.

A new method to reduce the statistical and systematic uncertainty of chance coincidence backgrounds measured with waveform digitizers
TL;DR: In this paper, a new method for measuring chance-coincidence backgrounds during the collection of coincidence data is presented, which relies on acquiring data with near-zero dead time, which is now realistic due to the increasing deployment of flash electronic-digitizer (waveform digitizer) techniques.

TL;DR: In this article, a new neutron counter for research experiments on nuclear fission has been developed, which is composed of a set of 3Heproportional counters arranged within a block of polyethylene which serves as moderator.
