Figure 6
Measurement points of the efficiency of the polarizer, neglecting the adiabatic RF flipper inefficiency and the 3He spin-exchange optical pumping (SEOP) filter efficiency, with an exponential guide to the eye. The performance is very good at 98.3% at the minimum wavelength of Å and approaches 100% for wavelengths around Å. The inset shows the analysing power of the 3He SEOP neutron spin filter with 94.5% polarization at 5 Å and 98% polarization at 12 Å. |
