Abstract

Theparticlelongitudinaldynamicsisaffectedbyerrors onthephaseandamplitudeoftheelectro-magneticfieldin eachcavitythatcauseemittancegrowth,beamdegradation andlosses. Oneofthecausesofthephaseerroristhechange of the ambience temperature in the LINAC tunnel, in the stubandintheklystrongallerythatinducesaphasedriftof thesignaltravellingthroughthecablesandradiofrequency components. Thefieldflatnesserrorofeachmultiplecell cavityiscausedbyvolumeperturbation,celltocellcoupling, tunerpenetration,etc. Inthispapertheinfluencesofthese twotypesoferrorsonthebeamdynamicsarestudiedand tolerancesforkeepingbeamqualitywithinacceptablelimits aredetermined.
