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.
