Abstract :
The symmetries of the chromatic correction sections in the SLC (Stanford Linear Collider) Final Focus System allow a high-resolution determination of the pulse-to-pulse energy fluctuations by exploiting the information from beam position monitors (BPMs) in regions of large dispersion. By correlating this signal with other BPMs, it is possible to infer the dispersion function as well as spatial components of transfer matrices anywhere in the arcs and Final Focus System without interrupting normal machine operation. Results from data recorded during periods of stable operation and when the linac energy was intentionally varied are presented
