Ring Status
This page should update about once every minute. If it doesn't, make sure you have JavaScript turned on. If it still fails, you can update manually by hitting reload or alt-reload (option-reload on a Mac).
The Popup Status shows only the status image (requires Javascript).
A text-based status page is also available.
Live beam-position data is available for insertion devices around the ring.
You can also view the Operations Group's Beam History Archives.
The Accelerator Status Hotline at (510) 486-6766 (ext. 6766 from Lab phones) features a recorded message giving up-to-date information on the operational status of the accelerator.
