- A new 5-station beamline for protein crystallography is being commissioned at the Swedish synchrotron light source MAX-II at Lund University. Of the 2K/gamma = 14 mrad horizontal wiggler fan, the central 2 mrad are used and split in three parts. The central 1 mrad will be used for a station optimized for MAD experiments and on each side of the central fan, from 0.5 mrad to 1 mrad, there are two fixed energy stations using different energies of the same part of the beam. These, in total five stations, can be used simultaneously and independently for diffraction data collection. The two upstream monochromators for the side stations are meridionally bent asymmetric diamond(111) crystals in Laue transmission geometry. The monochromators for the downstream side stations are bent Ge(111) crystals in asymmetric Bragg reflection geometry. Curved multilayer mirrors inserted in the monochromatic beams provide focusing in the vertical plane. The first side station is under commissioning, and a preliminary test protein data set has been collected. ©2004 American Institute of Physics

Journal article (peer-reviewed)abstract
- A beamline for macromolecular crystallography is under construction at the Swedish synchrotron light source MAX-lab at Lund University in a collaborative effort between Denmark and Sweden. Of the 7 mrad horizontal wiggler fan emitted from the new superconducting multipole wiggler, the central 2 mrad will be used and split in three parts. The central 1 mrad will be used for a tunable station optimised for multi-wavelength anomalous diffraction experiments and on each side of the central fan there will be two fixed wavelength stations using different energies of the same part of the beam. These in total five stations can be used simultaneously and independently for collecting diffraction data.

Conference paper (peer-reviewed)abstract
- A new beamline, Cassiopeia, at MAX II is about to come into operation. It consists of an energy-tunable station and four side stations intended for macromolecular crystallography. The X-ray source is a 3.5 T superconducting multipole wiggler installed in the 1.5 GeV MAX II storage ring. The energy-tunable station use grazing incidence Rh-coated silicon mirrors and an internally water-cooled Si(111) double-crystal monochromator while the four side stations use bent diamond and germanium monochromators and multilayer mirrors. This paper concentrates on the optics design of the energy-tunable station and also briefly describes other beamline components
