X-ray Source and Optics¶
13-ID-D uses a 2.1-m undulator with permanent magnets and a 27mm period (70 pole pairs) for the X-ray source. The undulator gap can be varied from 8.5 mm up to 150 mm, giving X-ray energies ranging from 5 keV and up.
A high-heatload liquid nitrogen-cooled double crystal monochromator is used to define the energy, using either Si(111) or Si(311) crystals, at ~25 m from the X-ray source. This monochromator works in fixed offset mode, with the offset putting the monochromatic beam 15 mm above the white beam. …
