title = "Neutron reflectometry and high-resolution imaging",
abstract = "This paper describes the thermal neutron reflectometer recently installed at the Rhode Island Nuclear Science Center (RINSC) and presents first results. The reflectometer utilizes a narrow 'pencil beam' with an adjustable angle of incidence on the horizontal sample surface. It permits reflection studies with the neutron beam slanting upward or downward in the range up to 0.03 radians allowing measurements to be made from above or from below (e.g., through the sample substrate). We report the results of measurements of specular reflectivity for liquid D2O, for Fomblin oil, and for a polarizing super-mirror. These results are in good agreement with expectation. We also discuss a proposed high resolution imaging device for ultracold neutrons (ΔQz = 10-9 angstroms-1). This resolution would constitute an improvement of two orders of magnitude beyond the currently available techniques. The imaging system utilizes a pair of hyperbolic mirrors and a flat horizontal mirror surface represented by a lake of Fomblin liquid.",
