Collimation and background reduction design for the time of flight neutron reflectometer SPEAR at LANSCE
Description
The effectiveness of neutron reflection measurements as a probe of surface and interface characteristics depends on the dynamic range of wave vector transfers over which the reflectivity can be measured, and upon the resolution possible within that range. We discuss some aspects of the design and our experience of the performance of the Surface ProfilE Analysis Reflectometer SPEAR at LANSCE with respect to collimation, wave vector transfer range and resolution and suppression of background.
