The In Situ Nanoprobe (ISN, 19-ID) beamline will be a new best-in-class long beamline to be constructed as part of the Advanced Photon Source Upgrade (APS-U) project*,**. To achieve long working distance at high spatial resolution, the ISN instrument will be positioned 210 m downstream of the x-ray source, in a dedicated satellite building, currently under construction***. The ISN instrument will use a nano-focusing Kirkpatrick-Baez (K-B) mirror system, which will focus hard x-rays to a focal spot as small as 20 nm, with a large working distance of 61 mm. The large working distance provides space for various in situ sample cells for x-ray fluorescence tomography and ptychographic 3D imaging, allows the use of a separate, independent vacuum chambers for the optics and sample, and provides the flexibility to run experiments in vacuum or at ambient pressure. A consequence of the small spot size and large working distance is the requirement for high angular stability of the KB mirrors (5 nrad V-mirror and 16 nrad H-mirror) and high relative stability between focus spot and sample (4 nmRMS). Additional features include fly-scanning a maximum of a 2 kg sample plus in situ cell at 1 mm/s in vertical and/or horizontal directions over an area of 10 mm x 10 mm. Environmental capabilities will include heating and cooling, flow of fluids and applied fields, as required for electrochemistry and flow of gases at high temperature for catalysis. To achieve these features and precise requirements we have used precision engineering fundamentals to guide the design process. We will discuss in detail the current design of the instrument focusing on the precision engineering used to achieve the stability, metrology, and positioning requirements.

The Advanced Photon Source (APS) at Argonne National Laboratory (ANL) is being upgraded to a multi-bend achromat (MBA) lattice storage ring which will increase brightness and coherent flux by several orders of magnitude. As part of this upgrade a total of 15 beamlines were selected to be enhanced to take advantage of the new source ’ these are designated as ’Enhanced Beamlines’. Among these is the enhancement to 2-ID, which includes an upgrade and move of the existing Bionanoprobe (BNP) from 9-ID [1]. This instrument will become the second generation Bionanoprobe II (BNP-II) with intent of studying cryogenic samples with sub-10 nm resolution. This upgrade requires a high performing metrology configuration and design to achieve the desired spatial resolution while adapting to the various constraints of the instrument. The cryogenic sample environment and detection constraints offer significant challenges for implementing a metrology scheme. In this paper we report on the new traveling interferometer configuration proposed for BNP-II.
