Operating Schedule

Beamline Schedules

Schedules for individual beamlines are posted in the ALS Scheduler.

Upcoming Long Shutdowns

The exact duration of the shutdown beginning on July 4, 2022, will be known in late spring, but we expect it will be less than eight weeks.

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.

Current Operating Schedule

Both current and upcoming schedules are subject to change depending on COVID-19 status. The “Restricted” label attached to user shifts indicates that beamtime/experiments will be subject to COVID-19 safety requirements. Note that the operating schedule displayed below reflects an extension of the winter shutdown and delay of returning to user operations compared with the originally published schedule.
