MXCuBE control of FLEX-HCD sample changer

11th MXCuBE meeting, 12-13 June 2017, SOLEIL Synchrotron, Saint Aubin, France

presented by Matias Guijarro, Beamline Control Unit, Software Group, ESRF

What is FLEX-HCD ?

  • Joint EMBL-ESRF development
  • Staubli 6-axis robot arm + sample grippers + High Capacity Dewar
  • 8 cells of 3 containers each - container can be for SPINE or Unipuck samples

What is FLEX-HCD ?

FLEX-HCD movie

Now installed in all ESRF MX beamlines :)

  • ID30B: EMBL beamline, first installation
  • ID23-1
  • ID29
  • ID30A-3
  • ID23-2

 

(ID30A-1 has the ESRF Robodiff, almost the same hardware but robot arm is the goniometer head)

Now installed in all ESRF MX beamlines :)

Conclusion

Mastery of how the FLEX-HCD operates

  • low-level control written by D. Nurizzo (ESRF)
  • higher-level control in Python (BLISS, MXCuBE hardware object, D. Nurizzo + M. Guijarro)

Generic sample changer makes it easy to integrate any sample changer within MXCuBE

Robust architecture, easy to debug in case of problem thanks to BLISS shell

Daily operation ; 15-20 samples per hour
