Abstract
Development of neutron spin filters based on polarized 3He is underway at Spallation Neutron Source (SNS). We report the progress of electrical heating tests in polarized 3He based on Spin-Exchange Optical Pumping (SEOP) method. We first test the system performance based on electrical heating via non-inductance heating pads. We observe a contribution of 955 hours to the relaxation time T1 from the heating pads. We then test the electrical heating SEOP pumping system at the SNS beamline Magnetic Reflectometer. We currently obtain 73% 3He polarization in a cell with 820 cm3 in volume.
