Figure 2
The X33 triangular monochromator setup. The beam aperture (1) limits the white beam footprint on the Si 111 blade (4). The crystal is cooled by a bath of liquid metal embedded in the water cooled metal block (2) and a bending mechanism (3) facilitates the focusing. A diode monitors the back scattering of a beryllium foil serving as a white beam monitor (5) (Be foil dismounted). A PT100 temperature sensor is mounted on the rear side of the crystals (6). |
