Schematic drawings of the monochromator. (a) Side view and (b) trimetric view of the goniometers. The azimuthal axis, , is on the goniometer. The Si crystal surface is located above the centre of the axis using a translation stage. Two arcs, x and y, are used to align the reflection plane perpendicular to the axis. The crystal is mounted on the goniometer in this way because of spatial restrictions caused by the BL6C beam pipe. |
