VARIOUS CANTING SCHEMES FOR UTILIZING MORE THAN ONE INSERTION DEVICE IN AN INSERTION DEVICE STRAIGHT SECTION

Presently, the APS utilizes one simple canting scheme for separation of radiation generated by two insertion devices (IDs) located in the same ID straight section. This scheme is based on triangular horizontal orbit bump with one corrector located between the IDs and orbit distortion limited to the ID straight section only. However, this scheme does not allow for switching between the upstream anddownstreamdevices, nordoesit allowforonebeamline to accept the combined radiation of both devices. These capabilities are being requested for future APS Upgrade. In this paper, we describe more advanced canting schemes that allow for these capabilities, and also present test results. The main complication here is that the orbit distortion is required to go through the storage ring magnets thus generating optics errors, which have to be corrected.
