BL 2-3

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).
