Abstract

At the SLS a fast orbit feedback (FOFB) has been designed to stabilize the closed orbit to the 1 mum level up to frequencies of 100 Hz. The feedback is integrated into the digital BPM system by means of 12 dedicated digital signal processors (DSP) and a fiber optic network. Submatrices of the "inverted" corrector/BPM response matrix are distributed to the BPM stations and corrections are performed in parallel. First promising commissioning results of the FOFB running at 4 kHz orbit sampling rate are presented. It is demonstrated that the chosen FOFB concept is appropriate and has the potential to reach or even exceed the design goals
