If a user loses more than 50% of their beamtime to a machine failure, beamtime will be rescheduled in the same round where possible and in the next available round if the current round is fully committed.
If a user loses all of their beamtime due to a beamline equipment/software failure, beamtime will be rescheduled in the same round where possible and in the next available round if the current round is fully committed.
The Australian Synchrotron will cover the costs of interstate users travelling to use their rescheduled time.
If a user is able to use 50% or more of their scheduled beamtime, beamtime will not be rescheduled, but the program advisory committee will be advised of large losses of beamtime and will be asked to take this into consideration when evaluating future beamtime allocations.
If a user loses significant beamtime due to their own equipment failure, or poor pre-experiment preparation further beamtime can only be secured with a successful proposal on a later round.
