| アブストラクト: |
Beamline I24 at Diamond is being designed in order to meet the challenges of structural biology of membrane proteins and large macromolecular complexes. Crystals of these molecules are notoriously difficult to grow to sizes appropriate for use on standard 3rd generation beamlines where beam sizes are typically 30 - 100_m. To address problems where crystals of only 30_m or less are available a dedicated microfocus macromolecular crystallography beamline is being constructed at Diamond. The beamline will be capable of delivering a focused beam of 5 - 100_m onto a crystal sample with high positional and high flux stability over a large range of frequencies. The beamline concept will be presented along with proposed solutions for improving the stability and quality of the focused X-ray beam.
