INSTALLATION PERIOD CURRENTLY SCHEDULED TO BEGIN APRIL 17, 2023

The APS Upgrade storage ring installation period, during which the APS will pause operations for one year, is currently scheduled to begin on April 17, 2023. The APS will operate throughout 2022 and will schedule an operations run early in 2023, though the exact schedule has not been determined. The upgraded APS will return to operations after the 12-month installation and commissioning period, though initial operations will be at reduced current and availability as the machine is tuned up. Regular updates will be provided on this website.
