Abstract
Neutron detectors designed to observe wide scattering angles are usually mono or linear detectors allowing the study of the reciprocal space along one direction only (linear multidetector or 2 or 3-axis spectrometers). The observation of a scattering plane has been typically developed for small angle neutron scattering experiments (SANS) [Citation1]. The SANS detectors are typically 2-dimensional multidetectors of large dimensions (∼1m × 1m), of relatively large elementary pixel size (∼ 0.01m × 0.01m), and limited pixel number. Because of these large dimensions, the limited number of the pixels, and also of the technique generally employed to select the wavelength (mechanical selectors provide a wavelength dispersion of about Δλ/λ ≈ 10–14%), the SANS resolution is low.
