    1. Two angle-resolved photoelectron spectroscopy systems equipped with Scienta analyzers are available for high momentum and high energy-resolution studies of solids at controlled temperatures ranging from 18 K to 370 K.

    The SES-200U system, primarily used for metal single crystal and epitaxial thin film studies, was recently upgraded with a sample introduction chamber. The system is designed for samples to be cleaned by thermal flashing or ion sputtering. The prep-chamber has a LEED system and a water-cooled evaporator shroud for three sources. The sample manipulator is computer controlled in the xyz direction as well as in the rotational axis along the z-direction. The data acquisition software allows experimenters to automatically map Fermi surfaces over a large region and take constant resolution scans as a function of photon energy. A 12 bit digital video system for online LEED analysis (to monitor film growth and sample quality), and a differentially pumped ion-gun are also part of the SES-200U system.

    The R4000 system, equipped with a sample introduction and transfer system, is mainly used for experiments that require in situ sample cleaving. Keeping in mind that the Scienta systems are in high demand, a prospective researcher should provide a detailed justification in their proposal to help the reviewers in their recommendations. For questions regarding the Scienta systems, please contact Mark Bissen at

    Attention Scienta Users: Please use the following links to access a form to check-out sample holders (R4000 only), information about dimensional data, and instruction manuals and reference documents.


    2. The Cylindrical Mirror Analyzer (CMA) chamber is a general purpose photoemission chamber based on a double-pass CMA. It includes capabilities for ion etching, sample heating and cooling, gas dosing, and invacuo sample introduction. In addition, a number of ports are available for evaporation sources, RGA measurements and other user instrumentation. Added features and their alignment must be compatible with the existing analyzer. User evaporation sources may be installed in the sample prep area of the chamber. For more information, please contact Mark Bissen at

    3. The Magnetic Circular Dichroism (MCD) chamber is available for MCD and magnetic linear dichroism (MLD) measurements of thin film magnetic materials. It is equipped with a 0.12 T electromagnet operated under computer control. Samples are typically prepared elsewhere, protectively capped, and transferred into the system. For more information, please contact Mark Bissen at

    4. The X-ray absorption chamber is currently configured for total electron yield measurements of solids in UHV. Special features include a load lock sample transfer system designed for invacuo introduction of multiple samples. The chamber can also be configured for partial electron yield (PEY) and fluorescence measurements. For more information, please contact Mark Bissen at

    5. An Infrared Microscope with programmable mapping stage coupled to a Fourier transform infrared (FTIR) spectrometer is available (6-micron spatial resolution, 650-8000 wavenumbers spectral range). It can be reserved in daily or weekly increments, and the time requirements should be noted on the proposal. In addition, a far IR experimental system is available for use in the range 200-2000 wavenumbers. Designed for the UHV study of surface adsorbates, it includes capabilities for sample temperature control and surface preparation and characterization. For detailed information on the capabilities of these IR systems, contact Ralf Wehlitz (

    6. The InfraRed ENvironmental Imaging (IRENI) beamline is a novel and unique addition to the conventional infrared system available at SRC. This beamline is the first infrared Focal-Plane-Array (FPA) imaging system coupled to a synchrotron light source. It provides high resolution, chemical images that are diffraction-limited at all wavelengths within minutes. The system features a Vertex 70 Fourier Transform infrared (FT-IR) spectrometer and a Hyperion 3000 IR/VIS microscope from Bruker, equipped with a liquid nitrogen cooled FPA with 128×128 pixels. The useful wavelength range is from 850 to 5000 cm-1 and the highest spectral resolution is 2 cm-1. In transmission the pixel size is 0.54×0.54 μm2 and each FPA block can cover a sample area of up to 52×52 μm2. FPA mosaics allow imaging of larger areas. While optimized for transmission it can also measure samples in reflection geometry. This beamline can be reserved in daily or weekly increments, and the experimental time requirements should be noted on the proposal. For detailed information on the capabilities of the IRENI beamline contact Carol Hirschmugl at

    8. SPECTRA stands for Students Performing Experiments Collaboratively Through Remote Access. This is a special purpose experimental chamber that is controlled through the web to allow anyone to make photoabsorption and photoemission measurements from preloaded research samples. The light for this system comes from the SRC storage ring and is processed by the Mark 5 Grasshopper to provide tunable monochromatic light. This system was designed to connect high school and college Physics and Chemistry students to a real experimental system and encourage them to continue their scientific studies. The SPECTRA connection can be found at the web-site: For more information and for scheduling contact Chris Moore at

    9. An Education and Demonstration Beamline is being developed to share the beauty and the excitement of synchrotron light, at SRC port 073. At present this beamline allows visitors to see the visible part of the light that is used by our researchers. Basic demonstrations are available and details of the synchrotron radiation can be displayed with a simple spectrometer system. In the near future we plan to have a darkroom with a functioning basic monochromator. This monochromator will be in air and accessible for some hands-on activities.
