There should be no password required. The broadcast will
 originate at the CAS conference room for those of you who would
like to meet in person. Those of you in Norfolk, it would be
nice for us to all meet!

Alexander Coxe, (Ph.D Thesis Summary Talk)

A 22 GeV CEBAF upgrade design is under development, and one of the necessary components is an automatic beam steering and optical correction system. Small environmental changes and system errors can lower beam quality or even shut down the machine; and in pursuit of the scientific mission of JLab, high quality electron beams must be delivered to the experimental hall on a predictable schedule.

Correction in the novel FFA arcs of the current upgrade design is complicated by several factors, which are shown to inform the design response of  corrector magnets to accelerator diagnostics. A baseline algorithm which both successfully corrects beams with realistic errors for a given arrangement of corrector magnets is proposed, with simulation results to show its effect. Several possible extensions of the algorithm are discussed. This work presents an important proof of concept for the FFA at CEBAF design effort, and provides a functional correction strategy which may be simply adjusted and optimized for any future design changes.
