“…Diffracted intensity measurement at low scattering angles can tolerate large uncertainty in neutron wavelength, enabling SANS at a relatively low intensity pulse neutron source. The performance of the time-of-flight SANS at PC-CANS can be directly compared with the SANS facility at the Low-Energy Neutron Source (an early CANS prototype in Indiana) [29] and at the McMaster Nuclear Reactor.…”

Canada's access to neutron beams for neutron scattering was significantly curtailed in 2018 with the closure of the National Research Universal (NRU) reactor in Chalk River, Ontario, Canada. New sources are needed for the long-term; otherwise, access will only become harder as the global supply shrinks. Compact Accelerator-based Neutron Sources (CANS) offer the possibility of an intense source of neutrons with a capital cost significantly lower than spallation sources. In this paper, we propose a CANS for Canada. The proposal is staged with the first stage offering a medium neutron-flux, linac-based approach for neutron scattering that is also coupled with a boron neutron capture therapy (BNCT) station and a positron emission tomography (PET) isotope station. The first stage will serve as a prototype for a second stage: a higher brightness, higher cost facility that could be viewed as a national centre for neutron applications.

“…The aim of this research is to investigate the response of the Micromegas detector to the LEN beam. The LEN detector is used for the detection of elements and materials as an progressive method for non-destructive testing (NDT) [18], neutron radiography [19], advancement of innovate instrumentation [20,21], small angle neutron scattering (SANS) [22] and Boron neutron capture therapy (BNCT) [23]. The source used in the simulation was a standard 60 keV neutron source with a flux of 5 × 10 6 neutrons/s, neutrons of which were created due to the departing protons from an accelerator striking a lithium target [24].…”

Micromegas detector has recently been used for high-energy neutron (HEN) detection, but the aim of this research is to investigate the response of the Micromegas detector to low-energy neutron (LEN). For this purpose, a Micromegas detector (with air, P10, BF 3 , 3 He and Ar/BF 3 mixture) was optimized for the detection of 60 keV neutrons using the MCNP (Monte Carlo N Particle) code. The simulation results show that the optimum thickness of the cathode is 1 mm and the optimum of microgrid location is 100 µm above the anode. The output current of this detector for Ar (3%) + BF 3 (97%) mixture is greater than the other ones. This mixture is considered as the appropriate gas for the Micromegas neutron detector providing the output current for 60 keV neutrons at the level of 97.8 nA per neutron. Consecuently, this detector can be introduced as LEN detector.
