A new monochromator was installed this week at Beamline 4.0.1-2 at the Advanced Light Source. This is a new beamline designed for the spectroscopy of magnetic materials. It features a high spectral resolution monochromator and a new type of undulator which can directly produce high brightness, high flux beams of circularly polarized x-rays. Tony Young is the project leader. Photo by Roy Kaltschmidt (XBD9811-02906-08.jpeg)
