Additional Laboratories to Which Users Gain Access
Users have access not only to the six Foundry Facilities, but also to equipment and staff of Affiliated Foundry laboratories that offer capabilities that the Foundry does not. User access to these laboratories is requested and managed in the same manner as access to the Foundry laboratories. These laboratories conduct research in the areas of Fabrication and Synthesis, Characterization and Theory
Users also have access to other divisions of the Lawrence Berkeley National Laboratory, including
The National Center for Electrom Microscopy
The National Energy Research Scientific Computing Center

Techniques available in a single, multi-technique experimental system include dichroic and spin-resolved photoelectron spectroscopy, diffraction, and holography; soft x-ray emission and resonant inelasic x-ray scattering; and soft x-ray absorption spectroscopy. New methods have been developed for studying buried solid-solid interfaces via soft x-ray standing waves and for imaging local atomic structure via photoelectron and x-ray holography. An ultrahigh-speed multichannel detector also makes photoelectron spectroscopy with high time resolution possible.
