An enhancement design of an existing 26-ID nanoprobe [1] instrument (NPI) at APS is being completed as part of work for the APS-Upgrade (APS-U) project. As part of this enhancement design, a new vacuum chamber geometry configuration has been implemented that balances the desired simultaneous x-ray measurement methods with accessibility and serviceability of the nanoprobe. The main enabling feature on the vacuum chamber is a slanted mid-level vacuum sealing plane. The new chamber design geometrically optimizes the ability to perform simultaneous diffraction, fluorescence and optical or laser pump probe measurements on the sample. A large diffraction door geometry is strategically placed near the sample for ease of access. The newly designed chamber can be readily serviced by removal of the upper chamber section, on which most larger instrument assemblies or beamline attachments are not interfaced. The mechanical design intent and geometry of this chamber concept is described in this paper.
