Special Capabilities
Fresnel zone plates are used to focus the beam. Configurations for high resolution and high flux can be chosen during the experiment: i) A near-field stack of two zone plates (D = 160 um) provides a probe size of 0.4 mm x 0.3 mm (5 x 10^8 @10 keV). ii) A single zone plate (D = 320 mm) provides ~10x increased flux (5 x 10^9 ph/sec @ 10 keV) at reduces resolution (0.6um x 0.4um). An environmental specimen chamber is optimized for bio-medical and environmental specimens. Kinematic mounting of the specimen allows correlation with Leica DMXRE Epi-fluorescence microscope. (Plunge freezing and freeze drying available for specimen preparation.) Robotic arm enables remote changing sample.

Software
The beamline is run using LINUX workstations using various EPICS-based applications. A user interface allows simple operation for users with little prior beamline experience. Custom software MAPS and XRF-Maps allows analysis of full fluorescence spectra at each pixel.
