Description

This work discusses the development of structured cathodes of various configurations coated with 10B4C for thermal neutron detectors. The cathodes are made of 50 μm thick aluminum foil and have a Λ-shaped surface. The feasibility of using structured cathodes is evaluated based on theoretical calculations of the single-layer thermal neutron detector efficiency as a function of the Λ-shape ridge height, the apex angle, the distance between adjacent ridges, as well as the neutron wavelength and the 10B4C coating thickness. Numerical simulations were performed using the Geant4 software package.
