Argonne Physics Division - ATLAS

Proposals and LOIs Approved at the May 9-10, 2022 ATLAS PAC Meeting

Requested beam time

The ATLAS Program Advisory Committee (PAC) met on May 9-10, 2022. A total of 65 proposals and letters of intent requesting 562 days of experiment 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: this beam time allocation is reserved for experiments that must be run at all costs
Priority II: this beam time allocation reserved for experiments that should be granted beam time if at all possible. The time allocated for Priority II experiments expires after 2 PAC cycles (i.e. it is valid for the present PAC cycle and the next one).
