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. Return to user operations has been delayed. User operations were originally scheduled to resume on March 30, and we presently estimate a delay of up to two weeks because of a delay in completing the linac modulator replacement project, the largest and most complex upgrade of the ALS since the addition of the superbends. 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.

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, per above, 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.
