ALS Automounter

F1 provides doubly-focused monochromatic X-rays, originating as half of the fan of radiation from the 24-pole 1.2 Tesla CHESS East wiggler (the other half feeds F2). A white-beam collimating mirror located upstream of the F1 and F2 monochromators reduces the heat load on the optics as well as aiding in focusing. The horizontally-focusing F1 monochromator is located 20 meters from the source, and a vertically focusing mirror is located 0.68 m downstream of this. The final focused beam has 1 mrad horizontal and 0.4 mrad vertical divergence. The working focal point is 4-6 meters beyond the focusing mirror. 1

Automated Systems at F1:

MacCHESS has an ALS-style crystal automounters available at beamlines A1 and F1. The F1 automounter is a BAM-1 model with pneumatic actuators, while the automounter at A1 is a BAM-2 with a 3-axis Cartesian robot. Both accept Uni-pucks and ALS pin bases with 18 mm pins. The F1 automounter also accepts the earlier ALS pucks. 2
