SANS Window Information
This magnet's tail set contains SANS windows that greatly decrease small angle neutron scattering to and from the sample when compared to a normal aluminum tail set. One set of windows is aligned through the bore of the magnet (along the field) and the other through the split (perpendicular to the field). Neutron access to sample for a 25mm distributed sample volume is +/-5 o along the bore or +/-3 o along the split. Contact a SANS scientist for information on small angle neutron scattering and related experiments.
