APS Operations and General User Programs During the COVID Pandemic
BioCARS is a national user facility for synchrotron-based, dynamic studies in structural biology, located at Sector 14 of the Advanced Photon Source, at Argonne National Laboratory. BioCARS is an integral part of the multi-disciplinary Center for Advanced Radiation Sources (CARS) run by the University of Chicago.
The mission of BioCARS is to provide state-of-the-art X-ray facility, scientific and technical expertise and support to enable users to study the dynamic properties of biological macromolecules by X-ray scattering techniques: time-resolved diffraction and solution scattering (SAXS/WAXS). In hybrid mode of the APS storage ring, BioCARS 14-ID beamline provides high polychromatic flux, with a number of photons per 100ps pulse approaching that of free electron lasers (such as the LCLS). Short X-ray pulses are synchronized with ps or ns laser pulses for conducting pump-probe time-resolved experiments. We are currently developing methods for serial Laue micro-crystallography to facilitate studies of irreversible reactions while minimizing sample consumption. We are also implementing electric-field jump as a method for reaction initiation and studies of protein dynamics. The overall goal of time-resolved experiments is to understand basic biological processes in structural and dynamics terms, on time scales from 100 picoseconds to seconds.
*As of February 6, 2017, BioCARS facility is decommissioned as a BSL-3 laboratory. BioCARS is now approved for research up to the BSL-2 level.
