Proposals and LOIs Approved at the May 22-23, 2023 ATLAS PAC Meeting
Requested beam time
The ATLAS Program Advisory Committee (PAC) met on May 22-23, 2023. A total of 60 proposals and letters of intent requesting 444 days of facility time were evaluated. The considerations of the committee were based on their assessment of the scientific importance of the proposed research, its technical feasibility, and its reliance on aspects of the ATLAS facility that are unique.
Types of approval
Because of the large number of high-quality proposals and the constraints on beam time, the PAC is asked to recommend beam time allocation in two categories:
Priority I: used for experiments that must be run at all costs
Priority II: used for experiments that should be run if possible. The time allocated for Priority-II experiments is valid for 2 years (roughly 2 PAC cycles), starting from the date of the PAC meeting when it was approved. If Priority-II experiments cannot be scheduled before the approved time expires the corresponding proposals will have to be resubmitted.
PAC meeting outcome
Below is a table with the proposals approved by the ATLAS director based on the recommendations of the PAC. The last two columns indicate the number of days approved. Priority-II days expire on May 23, 2025.
