[en] The first XUV beamline (200-2000 eV) at NSLS-II will have two branches, one optimized for photon hungry experiments requiring high coherent flux and one optimized for studies of polarization sensitive materials and interfaces based on fast polarization switching. We describe here the branch designed for fast polarization switching with frequencies up to 1 kHz, high photon flux, and good energy resolution. The beamline will be served by two canted undulators and is based on the focusing variable line spacing grating monochromator. The two beams will be focused at the same spot of approximately 80x10 μm (hor.xver.). The expected circular polarized flux at the sample from each device up to 1.4 keV will be higher than 10¹² photons/s at a resolving power better than 10⁴. An additional KB focusing system will deliver the two beams to a spot in the μm range.
