“…This extension is required to match the neutron detector of the BRIKEN project [17]. The DACQ has been also applied to other types of detectors like liquid scintillation detectors for neutron detection [32] and a NaI(Tl) total absorption γ-ray spectrometer [33].…”

A new detection system for the measurement of beta-delayed neutron emission probabilities has been characterized using fission products with well known β-delayed neutron emission properties. The setup consists of BELEN-20, a 4π neutron counter with twenty 3 He proportional tubes arranged inside a large polyethylene neutron moderator, a thin Si detector for β counting and a selftriggering digital data acquisition system. The use of delayed-neutron precursors with different neutron emission windows allowed the study of the effect of energy dependency on neutron, β and β-neutron rates. The observed effect is well reproduced by Monte Carlo simulations. The impact of this dependency on the accuracy of neutron emission probabilities is discussed. A new accurate value of the neutron emission probability for the important delayed-neutron precursor 137 I was obtained, P n = 7.76(14)%.

“…Scintillators are relatively resistant to radiation doses, such that the fast neutron fluences above 10 11 ÷10 13 n/cm 2 (depending on detector size and material) lead to some loss of light yield and transparency. Thermal neutrons can also be detected by the scintillators through 6 Li/ 10 B/ 157 Gd loading in small fractions (<8% by weight).…”

“…Thanks to PSD and good timing this scintillator may allow a simultaneous neutron and charged particle detection [5], substituting CsI(Tl) crystals, widely used in nuclear physics. NEDA Collaboration is also implementing modern PSD methods: on-line one, based on SIS3302/50 digitizers (eventually on custom FADC) [6], and off-line one, using the Neural Networks.…”

“…The neutron energy resolution typically depends on the duration of the source pulse and on the timing of detector signal. The conversion of the incident neutron into charged light nuclei only, in some cases ( 3 He, 6 Li), can be used to measure the neutron energy through the calorimetry.…”

Neutron detection is a broad field for fundamental research and applications. Its development is presently following an evolutionary scenario when the known detector technologies are being improved in their performances. Important advances are made by developing Pulse Shape Discrimination capable plastic and polysiloxane scintillators, which combine n/γ separation with handling simplicity of solid scintillators. GEM and MicroMega detectors promise to make a breakthrough in the neutron imaging applications, providing a good spacial resolution combined with a large detector area. Diamond detectors allow to exploit the semiconductor detector advantages in very high neutron fluxes of fission or fusion reactors. These and many other developments are ongoing and will be implemented in upcoming experiments and applied research facilities. INFN Workshop on Future Detectors for HL-LHC
