Synchrotron light sources are now transitioning to 4th generation storage rings with several new sources and upgrades of existing facilities around the world with the goal of decreasing the electron beam emittance, increasing the x-ray beam brightness and increasing the coherence of the x-ray beam with the goal of transforming x-ray science. The $815B Upgrade of the Advanced Photon Source at Argonne National Laboratory is currently underway and will be the brightest ring-based x-ray source in the world when in the world with the commissioning of the new storage ring planned for early 2024. I will describe the accelerator science and technology efforts in support of this upgrade as well as other light source accelerator activities at Argonne.
