Abstract: Superconducting accelerator technology has demonstrated its superior performance in large scale machines such as CEB A at TJNAF and is increasingly used for new accelerator designs. Until now tins technology has found its main application in electron accelerators. However nowadays proton accelerator designs for the European Spallation Source (ESS) and the Accelerator Driven Transmutation Technology (ADTT) also study the feasibility of superconducting linacs. In contrast to the highly relativistic electron beams the proton beam exhibits an increased susceptibility to voltage fluctuations in die acceleration system induced by microphonics and dynamic Lorentz force detuning. Aldiough low beam loss is an important criterion for linac design, studies of die longitudinal dynamics appear to be a good indicator for beam stability in presence of fluctuations of die accelerating field. Control of die vector sum of multiple cavities driven by one klystron is desirable for cost reasons but does not allow for control of individual cavity fields. In diis paper we study die performance of such a system.
