BL 2-3
Micro-focus hard x-ray imaging and micro x-ray absorption spectroscopy
Ideal for obtaining elemental maps of small samples (10 microns - 25 mm) as well as performing spectroscopy on selected points in the sample
Source: 1.3 Tesla Bend Magnet, 0.75 mrad acceptance
Monochromator: Water cooled, double crystal Si(111)
Energy range: 4.9 - 23 keV focussed (please contact for experiments above 19 keV)
Energy Resolution:
Beam size on sample: 1 micron OR 5 micron diameter axially symmetric focusing optics
Flux on sample: ~10^9 photon/sec (see image)
Detector: Single element Hitachi Vortex 90EX, 50mm^2 area
Detection system: Xspress3, Zebra and V2F100
Max count rate: 3 million counts per second
Practical element detection: SiK - NbK, most L-edges (concentration dependent)
Sample Environment: Ambient temperature and pressure, biological cryo cell available on request
Sample mounting:
Primary mode is the "Wheel of Fortune"optimized for thin sections. Samples are mounted to cassettes that push fit into a wheel that can hold up to 6 cassettes (see gallery and CAD below).
