IMSSSeminar DATE: 2011-12-09 10:00 - 12:00 PLACE: PF 2F Meeting room TITLE: （11-32）IMSS Seminar: The Long-wavelength Macromolecular Crystallography Beamline at Diamond Light Source CONTACT: yusuke.yamadakek.jp SPEAKER: Diamond Light Source  (Diamond Light Source) LANGUAGE: English ABSTRACT: Beamline I23 at Diamond Light Source will be a dedicated beamline for long-wavelength phasing experiments from macromolecular crystals. It will operate in a core wavelength range of 1.5 to 4 遵ｧ, offering a complementary setup to the suite of already five existing MX beamlines. To minimize absorption effects, the complete beamline will be operated in vacuum. An X-ray tomography setup will be integrated into the experimental end station to determine the crystal shape and size as a basis for an analytical absorption correction. A large curved detector will allow access to diffraction data up to 2θ = ±90潤・ After a brief overview on the latest status of Diamond and its MX facilities, the presentation will address both the challenges of in-vacuum long-wavelength macromolecular crystallography and the opportunities by extending the wavelength range towards the sulfur and phosphorous K-absorption edges and report on the current status of the beamline project.
