      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

      Source Type
      Elliptically Polarized Undulator (EPU49)

      Optical System
      CSX-1 consists of a first (M1A) plane mirror, a VLS-PGM and a spherical bent mirror (M3A) resulting in a spot at the exit slit of ~20 um. The exit slit can be located ~1m upstream of the endstation to provide an ~200 um beam in the endstation or located in the endstation for coherent diffraction studies.

      Experimental Apparatus
      In-Vacuum Spectrometer with FastCCD (960x960 at 100Hz)

      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.
