Reliability of Target Ion Source System on SPIRAL1 - GANIL
Résumé
The SPIRAL1 facility at GANIL produces radioactive ions beams (RIB) since 2001. Target Ion Source
Systems (TISS) employed are exposed to severe dose rates, requiring both simple and radiation hard
technologies. Moreover, the production is performed in a Nuclear Installation Plant, where all the
processes must cope with constraining safety rules. Once the TISS is irradiated by primary beams
of heavy ions, the dose rate, the activation level and the potential contamination in the surrounding
of the TISS make the access and the maintenance prohibited. All parts of the production system
must thus be highly reliable. An important process for the preparation, operation and recycling of
the TISS has been developed to minimize the failure probability and optimize the availability of the
beam for the users.
