The Versatile Macromolecular X-tallography in-situ (VMXi) beamline is an entirely automated facility for characterisation of, and data collection directly from, crystallisation experiments in situ.
As VMXi is operational in optimisation phase, the specification here gives the current beamline status.
|Available energy (keV)||12|
|Available wavelengths (Å)||0.95|
|Beam size at sample||10x10 µm2 min|
|Photon flux at 14 keV||DCM 2x 1012 ph/s|
|Techniques||Automated screening and interactive data collection of samples in standard CrystalQuickX and MiTeGen plates using wide band pass beam from multilayer-based monochromator|
|Key performance parameters||Ability to screen 4000 100 µm2 regionds of interest in 24 hours. Accuracy between off-line and on-line position of samples shoudl be better than 0.5µm.|
|Sample environment (cryostats etc.)||20 °C sample environment. Local storage, sample visualisation,dedicated goniometer|
|Robot/Sample manipulation||Plate handling robot for automated handling. 10 second exchange time between sample position and local storage. 1 minute exchange time between local storage and long-term storage|
