X10SA (PXII) Beamline Calendar

User proposals are accepted for collaboration projects with the MS2 Microspectrophotometer (UV/Vis absorption, fluorescence, (Resonance) Raman spectroscopy). These will be conducted in the PSI in-house research time

For standard X-ray diffraction data collection, there is no public proposal system for X10SA. The available time is divided between the partner institutions.

Morning Shift 10:00 - 18:00 10:00 - 18:00
Evening Shift 18:00 - 02:00 18:00 - 02:00
Night Shift 02:00 - 10:00 02:00 - 10:00ALERT!
ALERT!Note that due to machine shifts, the Night Shift from Monday to Tuesday ends already at 7 AM Tuesday morning. This also applies to Night Shifts preceding shutdowns.


Please note that the entire shift is 8 h but the actual measurement time officially starts one hour after the allocated shift starting time to allow setup and loading/removing of pucks in the robot sample changer. Still, the local contact will let you know if you are able to start earlier.

  • The beamtime has to be cancelled at latest 2 weeks in advance, otherwise the shifts will be fully deduced from the number of available shifts.
  • In case the user provides a substitute with a valid proposal within the 2 week period the shifts will be deduced from the proposal of the substitute.
  • The same rules and cancellation period hold for proprietary beamtime, with the difference that the shifts will be charged to the customer even if they are not used.
  • The information about shift cancellations must be sent to the responsible beamline staff as well as to the local contact of the corresponding date if already assigned.
  • The duration of the shift comprises setup of the beamline and possible loading/removing of samples in the robot.
