BM14 is bending magnet 14 beamline at the ESRF, optimised for exploiting anomalous scattering methods MAD/SAD in macromolecular structure determination. BM14 has an optical design suited to the rapid and accurate energy change between 7 and 17 kev, which covers most of the commonly used absorption edges of heavy atoms. BM14 provides beamtime and support to scientists from India (via Department of Biotechnology (DBT) funding) and Europe (via European Synchrotron Radiation Facility (ESRF) funding and the BioStruct-X European Commission Programme) on the basis of peer-reviewed beamtime proposals.
