The crystallography beamline I711 at MAX II

Area of Science:

• Materials Science
• Crystallography
• Synchrotron Radiation

Background:

• The MAX II synchrotron facility in Lund has introduced a new X-ray beamline.
• This beamline has been operational since August 1998, supporting various diffraction techniques.

Purpose of the Study:

• To describe the capabilities and instrumentation of the new X-ray crystallography beamline.
• To highlight its utility for macro- and small-molecule diffraction, as well as powder diffraction.

Main Methods:

• Utilizes a 1.8 T multipole wiggler as the radiation source.
• Employs a bendable mirror for vertical focusing and an asymmetrically cut Si(111) monochromator for horizontal focusing.
• Operates within a wavelength range of 0.8-1.55 Å.

Main Results:

• Achieves a measured flux exceeding 10^11 photons/s at 1 Å for a 0.3 mm x 0.3 mm sample.
• Currently equipped with Mar345 imaging plate, Bruker Smart 1000 CCD, and Huber Guinier camera.
• An ADSC 210 CCD detector is planned for installation in 2000.

Conclusions:

• The new beamline offers high flux and versatile capabilities for crystallographic studies.
• It supports a range of diffraction experiments, enhancing research potential at MAX II.
• Ongoing upgrades, including a new CCD detector, will further expand its scientific applications.
