Abstract

The unique advantages of using polarized ³He as neutron spin filters, such as broadband and wide angular acceptance of neutron beams, have made it widely used in most neutron facilities. Over the last several years, we have developed a polarized ³He program to meet the increasing needs of ³He based neutron spin filters at the Oak Ridge National Laboratory's (ORNL) High Flux Isotope Reactor (HFIR) and Spallation Neutron Source (SNS). At ORNL, polarized ³He is produced using Spin Exchange Optical Pumping (SEOP). We have constructed a ³He cell fabrication station to produce ³He cells of different pressures and dimensions. Two optical pumping stations have been built in the lab to perform ex situ pumping of ³He. A compact in situ ³He analyzer has been constructed and installed for the Magnetism Reflectometer (MAGICS) at SNS. A novel polarized ³He filling station for the Hybrid Spectrometer (HYSPEC) at SNS is under development.
