Figure 7
The measured polarization of the neutron beam as a function of wavelength with either one or nine neutron guides inserted. The polarization was determined from the flipping ratio, which was measured using a 3He spin analyzer. The red and blue data were measured in separate experiments. The larger beam divergence obtained with nine guides inserted causes a loss in beam polarization at wavelength λ = 5 Å. The error bars in all figures represent one standard deviation in uncertainty. |
