Description

We report the first results in the development of spin exchange optical pumping for use as a polarised 3He spin filter at the ISIS pulsed neutron source Helium polarisation of 35% in a cell of 0.8 bar has been measured with neutrons and 23% in a 1.6 bar cell with NMR. Also reported is the progress in developing magnetic environments. The characteristics of a few designs have been investigated by modelling, measurement of the magnetic field and relaxation of the 3He polarisation
