Operating Schedule

Beamline Schedules

Schedules for individual beamlines are posted in the ALS Scheduler.

Upcoming Long Shutdowns

The ALS is currently in a long shutdown. User operations are scheduled to resume on March 30, 2021. The summer shutdown is expected to begin in early July 2021 and last approximately three months, and we also anticipate a three-month shutdown beginning in January 2022.

Over the next few years, shutdowns will likely be longer than in recent years to allow the installation of the new accumulator ring, which is required to inject beam into the storage ring of the upgraded ALS, and the replacement of aging infrastructure in our 30-year-old facility in preparation for the new storage ring’s installation.
