Here, we present the upgraded Advanced Photon Source (APS) will be optimized to produce hard X-rays with a high degree of spatial coherence, and will exceed the capabilities of today's synchrotrons by two to three orders of magnitude in brightness and coherent flux in the hard X-ray range [1]. It will particularly benefit techniques such as advanced X-ray nanoprobes for nanoscale imaging, nanospectroscopy, and nanodiffraction. It will also benefit coherent diffractive imaging and ptychography with spatial resolution approaching atomic length scales and permitting time-resolved studies [2]. Meanwhile, many beamlines will be upgraded to take advantage of the smaller emittance for nanofocusing and nano-scale imaging. All of these methodologies will need novel precision X-ray instruments, including nanopositioning stages, to make full use of the new diffraction-limited storage ring capabilities. Although commercial companies produce a wide variety of state-of-the-art nanopositioning stages, there are specific scientific research goals that cannot be addressed adequately with commercial products. In these cases, it is necessary to push the engineering limits and develop in-house, customized nanopositioning stages to meet the scientific research goals. In this technical report, we outline the progress of mechanical designs of APS-developed nanopositioning instrumentation for synchrotron radiation instrumentation (SRI) applications. First, we describe flexure stages that use both overconstrained weak-link mechanisms and commercial flexure pivots. Finally, we describe a new, highly stable stage system for hard X-ray microscopy applications, called the Velociprobe.
