APS USER EXPERIMENTS HAVE PAUSED; YEAR-LONG APS UPGRADE UNDERWAY

The Advanced Photon Source is undergoing a comprehensive upgrade to replace its original electron storage ring with a new, state-of-the-art accelerator. This will increase the brightness of APS X-ray beams by up to 500 times, and new beamlines will be constructed to take advantage of these improved capabilities.

The upgraded APS will return to operation after the 12-month installation and commissioning period, although initial operations will be at reduced current and availability as the machine is tuned up. Beamlines will come online at different points following the shutdown. Every APS beamline will undergo operational, technical and scientific commissioning before restarting.
