Dependability Studies for CERN PS Booster RF System Upgrade

Radio frequency systems are a vital part of almost all accelerators. The request for a higher beam bright-ness from the injector chain of CERN's Large Hadron Collider, as demanded by the future High-Luminosity program, has motivated, among many other upgrades, the construction of new RF equipment in the PS Boost-er. Because availability and reliability have an im-portant impact on the luminosity production in a col-lider environment, dependability studies have been performed on the new design of the RF system assum-ing different maintenance strategies. This paper will present the model, made with the commercial software Isograph, for dependability studies. In addition, a comparative study will be presented between the re-sults obtained from Isograph and from an analytical analysis.
