Abstract
A new concept of medium resolution SANS measurements in a double bent crystal arrangement using fully asymmetric analyzer geometry was suggested earlier. This setup enables a positional analysis of the scattering curve and thus, to collect the whole spectrum simultaneously by a linear position sensitive detector (PSD). It is shown, on the basis of both calculations and Monte Carlo simulations, that the neutron beam can be focused at the PSD, which practically leads to the gain in angular resolution. These theoretical predictions are proved experimentally.
