Title: A Beam line for Macromolecular Crystallography in ALBA

Abstract

ALBA is a third generation 3 GeV storage ring being built near Barcelona and foreseen to be operational in 2010. Out of the seven beamlines already funded in ALBA, one will be dedicated to macromolecular crystallography (MX). The beamline, dubbed XALOC, shall cope with a broad range of crystal structures and sizes. To this aim, a flexible optical design involving variable focusing optics has been incorporated into the beamline optics. The photon source will be a 2 m long, in-vacuum undulator with a period of 21.3 mm. The optics will consist in a Si(111), double-crystal monochromator cryogenically cooled, and a pair of mirrors placed in a Kirkpatrick-Baez configuration. The beamline will deliver a high flux beam in the 5-15 keV energy range, with an energy resolution of {delta}E/E {approx}2 x 10-4. In addition to the main beamline, it is being considered the possibility to use a diamond laue monochromator to provide photons at a fixed wavelength to an ancillary branch. This report shows the present status of the beamline design.
