Beamline ID14 is an undulator beamline on a high-ß section dedicated to monochromatic macromolecular crystallography. Using three undulators, ID14-1/2 provide high brilliance at 13.3 keV, as well as limited tunability between 9.6 keV and 14.5 keV on ID14-4. Based on the Troika concept, this beamline has four stations: three side stations using thin diamond crystals and an end station with a double crystal monochromator and a toroidal focusing mirror. These stations are operated independently to allow four different user groups to collect data simultaneously.
The beamline has three undulators, all with a minimum gap of 16 mm and a length of 1.6 m. The first undulator, with a period of 42 mm, is tunable over a wide wavelength range. The second undulator of 23 mm is a single line undulator providing highest flux for experiments at 13.3 keV. The final undulator is optimised for Se edge experiments with the peak flux at around 12.7 keV.
ID23-1 and ID23-2
| Two canted undulators on a low-ß section (min gap 11mm) | U35 (for ID23-1) | U20.2 (for ID23-2) |

Beamlines ID23-1 and ID23-2 operate from a canted undulator section with an angular seperation of 1.5 mrad between the two X-ray beams. The U35 is a widley tunable undulator giving access to energies from 5 keV to 20 keV. The U20.2 undulators of ID23-2 is designed to be as monochromatic as possible with peak output at 14.2 keV.
