    SRC Users' Meeting

    The 2012 SRC Users’ Meeting is set for September 28-29, 2012. It will be held at the Physical Sciences Laboratory, 3725 Schneider Drive, Stoughton, Wisconsin (adjacent to SRC). Information on registration, submission of abstracts, Aladdin Lamp Award nominations, the poster session, and more can be found on the 2012 SRC Users’ Meeting website.


    SRC Beam Time Schedule

    The SRC Beam Time Schedules for the upcoming period of July 9 to December 31, 2012 are now available here.

     


    Size Matters --- Even for Molecules 

    Size MattersTwo electrons that are emitted from a large molecule by a single photon may originate from far apart within that molecule. In a recent study on hydrocarbon molecules consisting of one to five fused benzene rings (each ring consisting of six carbon atoms), SRC researchers Tim Hartman and Ralf Wehlitz have found that the relative probability for ejecting two electrons scales linearly with the length of the molecule.

    Visualizing Electronic Chirality and Berry Phases in Graphene Systems

    SRC Users Y. Liu, G. Bian, T. Miller, and T.-C. Chiang recently published a paper titled “Visualizing Electronic Chirality and Berry Phases in Graphene Systems Using Photoemission with Circularly Polarized Light.” This paper is also described in a viewpoint article. In addition, first author Yang Liu received a best poster award at SRC’s 2011 Users Meeting.  The work was done using ARPES with both circularly and linearly polarized light on the new U9 VLS-PGM beam line at SRC.

    SRC Funding Update

    With the NSF ending its stewardship of the SRC, the University of Wisconsin has stepped in with funding to ensure the operation of Aladdin storage ring through July 1, 2013. Financial realities will require a reduced scope of educational activities and research support, but full 24/5 operation will be available.

    Starting in January, user fees will be put into place to supplement the University contributions. In addition to allowing current graduate students to complete their work, this support will provide a bridge to new initiatives.

    The SRF electron gun program is moving forward vigorously with key procurements now in place for on-schedule installation early next year. Other avenues for further funding of Aladdin operations and work toward an FEL facility are being actively pursued to keep light source science at Wisconsin for years to come.


    New Imaging Technique Available at SRC

    A team of SRC Researchers led by Dr. Carol Hirschmugl has demonstrated a new imaging technique that offers high-resolution pictures of the molecular composition of tissues with unprecedented speed and quality.  This technique is made possible by a new facility called the “Infrared Environmental Imaging (IRENI),” which employs multiple beams of synchrotron light to illuminate a state-of-the-art camera. An article about the new facility appears in the March 21 online edition of Nature Methods.
