The Advanced Photon Source (APS) Upgrade Project is a major redesign of the current operating machine to a new multi-bend low emittance lattice operating at 6 GeV with 200 mA of stored beam. To fully support the APS Upgrade (APS-U), the front ends and insertion devices (IDs) located inside the storage ring tunnel need to be upgraded. Most of the front ends at the APS were designed more than 20 years ago and have limitations in the power handling capability. As part of APS Upgrade all the ID front ends will be replaced to one of two types – capable of handling the full straight section of IDs or canted with two ID beams. At the current time, the APS has 54 IDs in operation over 33 beamlines. Most of the devices were optimized more than 20 years ago for 7-GeV operation, providing full energy tunability in the hard x-ray range. To maximize the brightness and flux for all the beamlines (also part of the APS-U), most of the IDs will be replaced. This seminar will provide an overview of the plans for the front ends and insertion devices for the APS-U.
