Layout of the monochromators at the Medical Beamline ID17 of the ESRF. Two pairs of CT monochromators can be installed in the tank; at the moment only the pair in positions 3 and 4 are in use. The crystals can be tilted about horizontal axes, and the first crystal can be translated vertically and along the beam direction. The vertical offset of the beam is 40 mm. The first crystal and the beamstop can be lowered to allow the use of the dual-energy monochromator for coronary angiography, located downstream in another tank. |
