MAGIK

NSF: MAGIK Offspecular Reflectometer (MAGIK)

Neutron spin filters can be applied to measurements requiring different field orientations. The schematic shown above illustrates the use of NSFs on MAGIK. In this example, the NSF is the analyzer for a polarized beam measurement with a horizontal field. For more details concerning the neutron spin filter, please select the provided links for general {Chen03} and specific {Chen04} applications. For more info concerning the MAGIK instrument, please contact Brian Maranville or Joe Dura (contact info below).
