Understanding and improving the high field orbit in the Fermilab Booster

With the implementation of the BPM system in the Fermilab Booster, complete survey data of the main magnets have been used to determine magnetic moving schemes to correct the high field orbit at 8 GeV kinetic energy and to understand the global pattern of the high-field orbit in both planes. Considerable success has been achieved in the former tasks. Reasonable understanding in the latter effort was also obtained, given the multitude of factors that have to be addressed. An account is given of the survey record, the orbit correction exercise, and the effort to reconstruct the high-field orbit based on the survey records
