We report the status of the diagnostics undulator beamline for the Advanced Photon Source (APS) storage ring. The beamline was designed for the characterization of the 7-GeV, low-emittance positron beam at high resolution. The special diagnostics undulator has been manufactured by STI Optronics. The device exhibits very low magnetic field errors at closed gap of 10.5 mm: first field integral less than 15 gauss/spl middot/cm, and optical phase error less than 1.5/spl deg/. The front end of the beamline and a monochromator are installed and tested for use on divergence and directional stability measurements with a target resolution of 3 /spl mu/rad utilizing the first harmonic radiation of 25 keV. Initial results for the divergence measurement show that the storage ring is operating well within its design goals.
