Abstract

The digital global orbit feedback system for the storage ring of SRRC has been upgraded in terms of its feedback bandwidth extension by increasing its data acquisition sampling rate and compensating eddy current effect of vacuum chamber with filter. This orbit feedback system has been applied incorporate with the insertion devices operation, such as U5 undulator and engineering model adjustable phase undulator. Elimination of orbit drift and low frequency oscillation is a continuing effort
