BioSAXS Beamline
BioSAXS is a high brilliance X-ray beam with low scattering background and energy tunability, designed for anomalous SAXS experiments on biological-relevant metals, such as Calcium up to Molybdenum. The position of the beamline on a straight section of a 2m canted undulator permits different modes of operation.
With focusing abilities down to several μm, using Kirk Patrick-Baez optics and alternatively refractive Beryllium lenses, SAXS experiments in nanolitre volumes will be possible. Stray radiation will be eliminated by several sets of silts to facilitate a low intrinsic background of the beamline.
The end station will be equipped with highly automated and miniaturised sample environments for high throughput applications. Cryo-cooled sample holders and continuous flow-through micro capillaries will reduce radiation damage by the high flux X-ray beam provided by PETRA-III.

Proposed experimental capabilities
- Double crystal monochromator (DCM) mode
The DCM mode will be used as standard and allows SAXS experiments in small volumes with a good energy resolution; ASAXS will also be performed in this configuration - Multilayer monochromator (MLM) mode
The high flux of this mode permits time-resolved experiments down to the sub-microsecond level. - 'Pink beam' mode
The use of the raw spectrum of the undulator can be used for ultra-high flux experiments, such as 'few particle' scattering in highly diluted systems. In addition the coherence properties of the X-ray beam can be used.
