The undulator based beamline X13A at the National Synchrotron Light Source has been commissioned recently. The X13 undulator has an 8 cm period, and its first harmonic is in the energy range of 200--700 eV at the nominal ring energy of 2.5 GeV. The beamline uses horizontally deflecting optics. It consists of a SiC plane mirror, a water cooled entrance slit, a spherical grating, and two fixed exit slits. A flux of more than 10[sup 12] photons/s at 450 eV has been measured at X13A with an aluminum-oxide photodiode with a 200 [mu]m entrance slit, a 500 [mu]m exit slit, and a ring current of 242 mA. A VF[sub 3] absorption spectrum recorded at X13A shows the monochromator resolving power is at least 1000 at [similar to]500 eV with 30 [mu]m entrance and exit slits, in agreement with calculations. The X13A beamline will be used for x-ray coherence studies, spectroscopy, and multilayer reflectivity measurements as well as for x-ray instrumentation diagnostics.
