COVID-19 update: The allocation of beam time at the ALS continues to be affected by the pandemic. During this time, we are not publishing current proposal statistics or cutoff scores. Please visit this page for information on how the ALS is operating under COVID-19.
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 2020-1 Jan – Jun cycle.
