When this protocol is successful, users have the assurance that the beamline will give them data fitting with the quality assessment
Aim of this protocol: To help the LC startup the beamlines quickly and efficiently. Please use the log book to note current readings and anomalies.
Write down in the beamline logbook the following information :
- Date
- Experiment number (e.g. MX-415)
- Your name
- Your phone number on site and off-site, may also be written on white board.
Inside the experimental hutch :
- Check that the hutch is clean (if not note this in the log book and mail to BLSci)
- Check that all tools are in/on tool box/board
- Gloves and glasses are available to handle liquid N2.
- Glasses for laser protection.
- Check that no sample is on the goniometer
- Check that the cryo stream is aligned and working, level of N2 is ok, temperature regulation @ 100K
- Put the YAG screen on the goniometer (except ID23eh2)
- Check that exes_hutch is working - use it to align the YAG screen.
- Close the experimental hutch.
Align the beamline :
- Check that all applications needed on the end-station are running :
- Bliss device servers
- Front end and Vacuum applications.
- Spec oh
- Spec eh
- mxControlPanel (Id23-1,2 and Id29)
- mxCuBE : log in as users
- Firefox and ISPyB
- restart DNA (after logging into mxCuBE)
- Image viewer
- Do a Realign of the beamline (except ID23-1 -> use LC_startup in eh1).
- In the logbook write (in addition ID23-1 -> use LC_startup in eh1) :
- Machine status : ring current and operation mode.
- Check Front end is open.
- Check that automatic mode will last the experiment time.
- The energy if tuneable beamline
- Undulator Gaps
- The values of the diodes along the beam path with all shutters open and 100% transmission and slits open to beamline standard sizes (note also the gain)
- Check that these values fit the standards of the beamline (compare at least with values of the day before).
- With the safety shutter and fast shutter open, check that beam is centred.
Verify data collection with user account:
- Collect with mxCuBE at 1.7Å a blank image, should be free of beamstop artefacts.
- If test Xtals use one to collect images with mxCuBE at 1.7Å
- Same thing with DNA
- Check that ISPyB has been updated.
Sample changer:
- Check that the gonio head is the Smart Magnet head or miniKappa.
- Check that there is no baskets in the sample changer.
- If not tested before, put a test basket (with test samples) then test the sample changer (load/unload sample) using mxCuBE.
Safety and other stuff with users presence:
- Check that users have done their safety training.
- Explain about the oxygen level alarm and what to do if it sounds.
- Check that users know how to close the experimental hutch door.
- Check that users are confident with using the beamline.
- Check that users know the door code.
- Leave phone numbers where you can be contacted at all times (until 10 pm).
For ID23-2 only
- Note in logbook pressure on the KB vessel - check pressure sensor (blue device at the left side of the KB vessel) (985-1000 mbar).
- Check that helium cylinder (in the optics hutch electronic rack).
(If empty contact John Surr (working hours) or the floor operator (25 25)
