Abstract

Various orbit perturbations are enhanced after many insertion devices are installed in the storage ring of the TLS. These sources will interfere to system performance. The local orbit feedback system is used to suppress miscellaneous local orbit perturbation. The feedback system consists of a sensor and feedback control loop. The sensors are an electron beam position monitor (BPM) and photon monitor of the elliptical polarization undulator (EPU). The feedback control loop architecture share same hardware with global orbit feedback. The VME-based crates interconnected with high performance daisy-chained global reflective memory networks are used to share position data with DSP. The results are given
