As one of the latest beamlines at the Synchrotron Radiation SOLEIL facility, ANTARES beamline will offer an X-ray nanoprobe able to combine four powerful non-destructive techniques: (i) angle-resolved photoemission spectroscopy, (ii) core-level photoemission (X-ray photo electron spectroscopy), (iii) X-ray absorption spectroscopy and (iv) X-ray fluorescence. ANTARES microscope has implemented a powerful and innovative nano-scanning photoemission microscope technique using three independent detectors in combination with a 14 integrated-axes manipulator. Microscope motion requirements involve linear and rotary positioning based on non-magnetic ceramic servo motors, compatible with ultra-high-vacuum conditions. A complete four-head interferometer system monitors continuously, with nano-metric precision, the alignment of the sample and focalization optics during the scanning operation. An accurate electronic feedback avoids image distortion due to mechanical vibrations or thermal effects.
