A fully assembled module for the new APS storage ring. The new ring will be made up of 200 of these modules, combining precisely aligned electromagnets with a complex vacuum system and specially designed power systems.

Close-up of the connection between two magnets on one of the 200 modules that will make up the new APS storage ring. The vacuum system, which recreates the vacuum of deep space to keep the electron beam from coming in contact with the atmosphere, can be seen stretching between the two magnets.

Group shot of the team assembling modules for the new APS storage ring, gathered around the 100th fully assembled module. The new ring will be made up of 200 of these modules, built at a warehouse off of the Argonne site. Other completed modules can be seen in the background.

Argonne Laboratory Director Paul Kearns, seated, starts the countdown that shuttered the APS beamlines for the final time before the year-long APS Upgrade removal and installation period. Leaders from Argonne, the APS and the U.S. Department of Energy joined the celebration in the APS main control room.

Workers remove the first module of the original APS storage ring. The original ring will be completely cleared out to make room for the new one, which will be transported module by module to the APS facility and installed.

Members of the APS Upgrade team work on the first fully assembled sector of the new electron storage ring at the heart of the upgraded APS. The 1,321 magnets that make up the new storage ring will be assembled into 200 modules, and those modules assembled into 40 full sectors for installation at the APS.
