Presentation Transcript

  1. Diamond update and kappa activities • village structure • 19 operational beamlines • 5 operational MX beamlines • one MX beamline (I23) under construction • mini kappa devices bought for I04 and I04-1 • I23 will have kappa goniometer

  2. I02, I03, I04 MX end-station upgrade programme • high precision rotation axis • improved sample viewing and faster zoom • exchangeable mini-beam apertures • improved scatterguard • improved sample centring • improved beam diagnostics • easy beam visualisation • crystal annealing • camera system for rapid auto loop centring • finer attenuation control • new backstop design easier change between experiments at cryo or room temperature or a humidity controlled setup

  3. I02, I03, I04 MX end-station upgrade programme New experimental options • crystal humidity control • online spectroscopy • in-situ diffraction • tomography • easier remote operation • mini kappa • microfocus option with CRLs • mirror refurbishment programme underway (I02, I03, I04) • P6M on I03, I24 • P2M on I04-1 • new end-stations operational with user programme on I03 and I04 • I02 currently being upgraded

  4. I04-1 mini kappa use • in optimisation phase with friendly users • few user visits • STAC available as tab in GDA • device check at manufacturer • preparation for routine operation • integration with sample changer • software development and pipelines

  5. Data collection strategy, completeness 45 deg sweep 60 deg sweep • aligned thaumatin crystal • c* along spindle, a* along beam • different oscillation ranges 90 deg sweep

  6. Optimised data collection, effect of high kappa angle • Elena Kovaleva, Briony Yorke (Leeds) • enzyme P21212, 110.06 163.90 100.96 • two crystal forms, same problem • data completeness depending on overlaps • crystal orientation important kappa = 30 deg kappa = 90 deg kappa = 120 deg

  7. Long wavelength beamline I23
