Photon Energy5-28 keVRoutine operation 8-15 keV
Focal Spot50 - 200 nm
Measured:
98 nm @ 8 keV
62 nm @ 14 keV
Diffraction limited spot, the spot size is energy dependent. See doi.org/10.1364/OE.386068
Focused beam divergenceApprox. 1.2 mradEnergy independent.
Coherent FluxFully coherent beam:
6x1010 @ 8keV
3x1010 @ 10keV
8x109 @ 14keV

Flux at the sample position. Depends on energy, see Beamline Optics and doi.org/10.1364/OE.386068
2-circle GoniometerTheta:
stroke [-5, 90] deg
resolution: 10-4 deg

Phi:
stroke [-180, 180] deg
resolution: 10-4 deg
Theta is horizontal and perpendicular to the X-ray beam. Phi is perpendicular to Theta and vertical for Theta=0.

Note that the goniometer does not provide tomographic capabilities.
Coarse sample scanner (XYZ)stroke: 20 mm
resolution: 100 nm
In-house development
Fine sample scanner (XYZ)Option 1 (standard):
100 μm stroke in all directions

Option 2:
200 μm stroke in each horizontal direction
100 μm vertical stroke
NPXY100Z100-135
This option provides the stiffest frame and the highest resolution

NPXY200Z100-271
Accessible spaceApprox. 50 mm working space upstream of the X-ray focus.Always contact the beamline staff to discuss non-standard sample holders or environments.
Continuous scanningA single fine axis (X, Y, or Z) can be scanned continuously for fast mapping in 2D.

Energy scanningManual energy changes are possible on a timescale of minutes. Image stacks can be collected as functions of energy, but XANES and EXAFS measurements are not possible.
Off-line microscopyTwo optical microscopes are available for off-line sample inspection. One is a high resolution microscope (Olympus BX53M), the other a long distance stereo microscope (Olympus SZX16).

A Hitachi SU1000 electron microscope is also available at the beamline.
