Proposals are scored on a scale of 1 to 5, with 1 being the best score and 5 the worst. Reviewers are requested to use the following ranking schema:
- Must do
- High Priority
- Medium Priority
- Low priority
- Don’t do
Beam time is assigned based on each proposal’s score in relation to all other proposals for a given beamline. For beamlines where beam time requests exceed available beam time, a cutoff score is assigned after which no beam time is allocated.
The table below lists the percent of beam time shifts allocated/requested for each beamline and the cutoff scores after which no beam time was assigned for the 2023-2 Aug – Dec cycle.
