Wide Angle Spherical Neutron Polarimetry at Oak Ridge National Laboratory
Bulletin of the American Physical Society(2019)
摘要
The Spherical Neutron Polarimetry (SNP) Technique probes complex magnetic structures which are inaccessible by other methods. This technique is achieved by combining a zero-field sample chamber with full control of incoming and outgoing neutron polarization. While wide-angle SNP capability has been fully implemented in Europe, it is still in development in the US. At Oak Ridge National Laboratory, we are developing a wide-angle SNP capability suited for multiple neutron beamlines. The design is based on the basic concept of SNP while utilizing high-T-c superconducting films and Mu-metal. In this article we report our recent development of the SNP capability and its future applications.
