P12 EMBL BioSAXS Beamline
Work package 2.12
|
The described scientific case
of the BioSAXS beamline stands for a high brilliance X-ray beam with low
scattering background and energy tunability 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 the
different modes of operation. With focusing abilities down to several μm
using Kirk Patrick-Baez optics and alternatively refractive Beryllium lenses
SAXS experiments in nano-liter 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 miniaturized
sample environments for high throughput applications. Cryo-cooled sample
holders and continuous flow-through micro capillaries are constructed to
reduce radiation damage by the high flux X-ray beam provided by PETRA III.
Proposed Experimental Capabilities
-
Double single crystal monochromator [DCM] mode
The DCM mode will be used as standard and allows SAXS experiments in small volumes with a good energy resolution. Also ASAXS will 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.
