Software Q+A
Where can I run the data processing jobs?
Use the maschine hkl1 for all XDS, HKL2000, iMOSFLM jobs.
Hardware Q+A
I lost the beam, what shall I do?
Check whether the storage ring is filled. Check if something blocks the photon pass between the storage ring and your sample. This could be the main beamshutter, the experimental beamshutter, the MD2 fast shutter, the beam defining aperture (BDA) or the capillary.
The robot is not loading my sample, what shall I do?
Check whether or not you are using the correct vials. Only SPINE compatible vials from Molecular Dimensions are allowed for automated mounting. If the problem remains, try to open and close the sample-cap manually within the CATS-dewar, using the magnetic wand and retry the robot assisted mounting.
May I use 2theta to get a high resolution data set from a well diffracting crystal?
No. In principle the 2theta movement is is calibrated and ready to use. But due to geometrical considerations a high resolution data set (resolution better than 1.1 Å ) can not be collected by utilizing 2theta. Use a higher energy for the data collection instead to compress the diffraction pattern. On long-term you should apply for the dedicated high-resolution beamline BL14.2 if you expect your crystals to diffract to approximately 1.1 Å. The minimum sample-to-detector distance at BL14.2 is significantly smaller compared to BL14.1.
What is the minimal and maximal detector to crystal distance at BL14.1?
Minimal distance = 93mm
Maximal distance=730mm
