Commissioning of the FPGA Based Transverse Feedback System at the Advanced Photon Source
C.Yao, N.P.Di Monte*, W.E.Norum (ANL)
The Advanced Photon Source installed a Transverse Feedback System to correct the instability in the electron beam during single bunch mode. This instability manifests itself when a large amount of current is present in the beam. The only method currently formerly available to correct the instability was through chromaticity correction. The Transverse Feedback System deals with the instability without requiring changes to the ring chromaticity. Initial testing revealed issues with the input and output electronics. This paper will discuss these issues, their resolution and many other enhancements to the FPGA-based system.
