“…McGregor et al have developed a design based on 6 LiF in perforations, also a promising approach based on a 3d geometry. [1][2][3][4] Typically, thermal neutron detectors operate on similar principles, relying on an isotope with a high thermal neutron cross-section such as 3 He, 10 B, 6 Li,157 Gd and 113 Cd. An incident thermal neutron interacts with the neutron sensitive material, resulting in a nuclear reaction.…”
