Project Plans

Serial Crystallography on I24

For a closer look at the ongoing work: I24ssx board

Experiment types

• Extruder

  • Standard
  • Pump probe

• Fixed target (probably about 80-85% of serial on I24)

  • Standard chip collection – option for multiple exposures in each spot
  • Pump probe - see for short description https://confluence.diamond.ac.uk/display/MXTech/Dynamics+and+fixed+targets
    • Short delays
    • Excite and visit again
    • Long delays with fs opening/closing

• (Future) Fixed target with rotation at each “window” (Preliminary work done by beamline staff on the PMAC program https://confluence.diamond.ac.uk/display/MXTech/Grids+with+rotations)

Details of zebra settings for each type: https://confluence.diamond.ac.uk/display/MXTech/Zebra+settings+I24

Note that most of the set up for the fixed target is actually done by the PMAC via PMAC strings.

Ongoing list of things needed:

1. Solution for enabling users to run mx_bluesky instead of old scripts: blocked by permission issues. Preferred solution would be run on beamline kubernetes cluster - in the meantime also loooking into procserv as a possibility. (Fixing this should also allow us to stop using the Pilatus to make directories during an Eiger collection.) Temporary workaround in place for beamline staff, who should be starting to run this for testing/in house beamtimes.
2. Convert detector set up to use bluesky plans and ophyd_async devices. Investigate using the existing Pilatus in ophyd_async which writes HDF5 instead of CBFs (may want to make a CBF-writing Pilatus).
3. Start looking into moving away from edm screens towards a web-based GUI.
4. Improve alignment of chip: get it to work correctly for multiple zooms.

(TBC...)
