6-15 keV (with multilayer mirrors)
3-20 keV (without multilayer mirrors)

Monochromator

White light, multilayer mirrors in Kirkpatrick-Baez configuration

Calculated flux (1.9 GeV, 400 mA)

3 x 10¹⁰ photons/s at 12.5 keV

Resolving power (E/DE)

25 at 12.5 keV

Endstations

Characteristics

X-ray fluorescence analysis of samples with high elemental sensitivity and high spatial resolution

Spatial resolution

1.0 x 1.2 µm

Detectors

Si(Li)

Spot size at sample

1.0 x 1.2 µm

Samples

Format

Usually flat solids < 2 cm in diameter mounted between two layers of superclean polypropylene

Sample environment

Air

Special notes

By special arrangement, the focusing mirrors can be removed and white-light beam can be used (e.g., testing capillary optics, evaluating x-ray collimators)

Scientific applications

Trace-element analysis with high spatial resolution (e.g., silicon solar cells, GaN, atmospheric particulates, environmental soil samples, and biological samples), testing of x-ray capillary optics and new x-ray detectors
