Beam Dynamics Studies for the Fault Tolerance Assessment of the PDS-XADS Linac Design

Abstract

In order to meet the high availability/reliability required by the PDS‐XADS design, the accelerator needs to implement to the maximum possible extent a fault tolerance strategy that would allow beam operation in the presence of most of the envisaged faults that could occur in its beam line components. In this work, we report the results of beam dynamics simulations performed to characterize the effects of the faults of the main linac components (cavities and focusing magnets) on the beam parameters. The outcome of this activity is the definition of the possible corrective actions that could be conceived (and implemented in the system) in order to guarantee the fault tolerance characteristics of the accelerator. This work has been supported by the PDS‐XADS program, funded by the EU 5th Framework Program under contract FIKW‐CT‐2001‐00179.
