On April 20, 2024 the upgraded Advanced Photon Source (APS) took another important step forward, as the Accelerator Systems Division (ASD) team reported the first stored beam in the new storage ring.
After announcement of first electron turns in the storage ring, the accomplishment on April 20 shows a 0.15 mA beam current stored in the new ring. This feat demonstrates that the main storage ring systems – including 1,321 magnets, 2,247 power supplies, 560 beam position monitors, 1,104 meters of vacuum chamber, and 12 accelerating radiofrequency cavities – all function as designed.
