Title: Superbends expand the scope of Berkeley's ALS

Abstract

While the ALS has turned out to be a world-leader in providing beams of soft X-rays -- indeed, furnishing these beams remains its core mission -- there has nonetheless been a steadily growing demand from synchrotron radiation users for harder X-rays with higher photon energies. The clamor has been strongest from protein crystallographers whose seemingly insatiable appetite for solving structures of biological macromolecules could not be satisfied by the number of crystallography beamlines available worldwide. But how to provide these X-rays in a cost-effective way without disrupting the thriving research programs of the existing ALS users was the problem. Superconducting bend magnets (superbends) provided the answer for the ALS, which adopted a proposal to replace some of the normal combined-function (gradient) magnets in the curved arcs of the storage ring with superconducting dipoles that could generate higher magnetic fields and thus synchrotron light with a higher critical energy.
