      Beamline Description
      The CSX beamlines (CSX-1 and CSX-2) are served by two identical EPU49 sources. These EPUs serve the beamlines in three possible modes. 1) Both undulators in-line serving the CSX-1 branch to provide the highest coherent flux. 2) canted serving the CSX-2 branch to enable fast switching of two polarization states and 3) canted to allow simultaneous use of both branches.

      Technique(s)
      X-ray Absorption Spectroscopy
      X-ray Photoelectron Spectroscopy

      Research Types
      Soft x-ray spectroscopy: Catalysis and Other Chemistry Applications (In-Operando XAS, Ambient Pressure Photoemission)

      Source Type
      Elliptically Polarizing Undulator(s) (EPUs). The beam line optics permit use of one or both undulators in the 23 ID straight section.

      Optical System
      Variable line spacing - plane grating monochromator (VLS-PGM).

      Experimental Apparatus
      1. Ambient pressure photoelectron spectroscopy endstation with SPECS PHOIBOS 150 NAP electron analyzer. 2. In situ and operando X-ray absorption spectroscopy endstation with total electron yield and Vortex SDD partial fluorescence yield detector

      Computer System Hardware & Software
      Beamline components are controlled by EPICS. The user interface is through the Python and Control System Studio (CSS) clients. The user views the experimental system (sample and the surrounding environment) through CCD-coupled optical microscopes with Prosilica cameras. Linux Debian for running Workstations and IOCs.
