SLS and SwissFEL Backlog Policy
One chance to reschedule accepted beamtime, then cross-check by the proposal review committee:
Both you as users of our facilities and the teams operating the beamlines, and end-stations require planning reliability for conducting challenging experiments. Therefore, we schedule beamtime half a year ahead of time. During a pandemic, re-scheduling can sometimes not be avoided. However, if beamtime has been granted more than a year ago by the PRC, then both the principal investigator and the PRC should re-check if the proposed project is still up-to-date. Therefore, we introduce the 'maximum one chance to reschedule accepted beamtime due to pandemic' policy for all beamtime scheduled from 2021 onwards.
If a re-scheduled beam experiment cannot take place, then it will be listed in DUO as canceled, to allow a resubmission for cross-check by the PRC. We recommend that you briefly state 're-submitted due to COVID cancellation' to smoothen the process.
Please note that this holds only for accepted proposals, not for proposals on the reserve list. If proposals on the reserve list will be re-submitted then the status of the original proposal will be automatically changed to 'rejected'. Towards the end of a semester, we will set the status of proposals still on the reserve list to 'rejected' so that they can be resubmitted if desired.
