A Method for Aligning the Phases of C10 Cavities in the AD

The C10 cavities in the AD are used to rotate the injected beam distribution in the longitudinal phase space and then adiabatically debunch it, hence significantly reducing the momentum spread compared injection. The cavities must be correctly phased relative to each other and to the injected beam to maximise the transmission. This note summarises a method of phase alignment that was applied during the recommissioning after Long Shutdown 2 (LS2).
