The Advanced Photon Source Upgrade (APS-U) project will include a suite of new beam-lines. In preparation for this, a team at the APS is developing an X-ray microscope with a novel granite (Earth), air bearing (Wind) supported stage to take advantage of the two orders of magnitude increased coherent flux (Fire) that will be available with the APS-U. The instrument will be able to operate as a scanning probe for fluorescence microscopy and as a ptychoprobe for the ultimate in spatial resolution. Both are combined with tomography. The goals for the instrument while operating at the current APS are to demonstrate fast scanning of large samples at high resolution and ptychography at the highest resolution (speed and resolution limited by available flux). This presentation will discuss the unique mechanics, interferometry scheme, the advanced scanning control, and instrument integration.

Nanopositioning techniques present an important capability to support the state-of-the-art synchrotron radiation instrumentation research for the APS operations and upgrade project. To overcome the performance limitations of precision ball-bearing-based or roller-bearing-based linear stage systems, two compact linear nanopositiioning flexure stages have been designed and developed at the APS with centimeter-level travel range and nanometer-level resolution for x-ray experimental applications. The APS T8-54 linear flexure stage is designed to perform a precision wire scan as a differential aperture for the 3-D diffraction microscope at the APS sector 34, and the APS T8-56 linear flexure stage is designed for a horizontal sample scanning stage for a hard x-ray microscope at the APS sector 2. Both linear flexure stages are using a similar improved deformation compensated linear guiding mechanism which was developed initially at the APS for the T8-52 flexural linear stage *. The mechanical design and finite element analyses of the APS T8-54 and T8-56 flexural stages, as well as its initial mechanical test results with laser interferometer are described in this paper.
