BL 2-3

Beam line 2-3 is dedicated to 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

Practical element detection: SiK - NbK, most L-edges (concentration dependent)

 

Samples

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).
