Schematic drawing of the configuration to test a single foil flipper. Distances, sizes and angles are not to scale. To test the functioning of the foil flipper, the polarizer sets the neutron polarization in the positive vertical direction, the non-precession mode. In the SE(M)SANS modes the polarizer sets the neutron polarization in the horizontal direction. The arrow in the foil flipper indicates the direction of the magnetic field. The analyser can be oriented in the positive or negative direction to measure either the up or down intensity. |
