Abstract :
The global orbit feedback system for SPEAR will be upgraded in 1995 to achieve 30-50 Hz closed loop bandwidth. In this paper, we discuss issues related to measurements of the corrector frequency response, the DC response matrix, digital compensator design, and the impact of sequential BPM sampling. Results from detailed simulations are included
