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 brightness from the injector chain of CERN's Large Hardon Collider, as demanded by the future High-Luminosity program, has motivated, among many other upgrades, the construction of new RF equipment in the PS Booster. Because availability and reliability have an important impact on the luminosity production in a collider environment, dependability studies have been performed on the new design of the RF system assuming 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 results obtained from Isograph and from an analytical analysis.
