Comparison of polarized target materials in different magnetic fields

Tests were performed at the Paul Scherrer Institute (PSI) and CERN to determine the maximum polarization for two deuterated materials being considered for use in the SMC polarized target. The two materials studied were butanol and propanediol, both doped with Cr(V) complex. The maximum attainable polarization was found for magnetic field values of 2.5, 3.5 and 5.0 Tesla.
