Beamline Schedules
Schedules for individual beamlines are posted in the ALS Scheduler.
Upcoming Long Shutdowns
Until the ALS-U dark time, shutdowns will 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. In general, long shutdowns are expected to begin at the start of January and July and last ~13 weeks.
“SoftStart” indicates either a buffer period for contingencies arising after long shutdowns or periods when limited beamtime may be offered on a case-by-case basis. Any user beamtime scheduled for the SoftStart period should have the flexibility to be rescheduled for a later time.
The facility is undergoing an upgrade and will go dark to install the ALS-U storage ring. More information on the project timeline can be found here.
