AIRIX is a high current (19 MeV, 2 kA) electron linear induction accelerator used as a 60 ns single shot X-ray source for hydrodynamic experiments. As single shot experiments are performed with the AIRIX facility, the best performances and a high reliability level must be met for each experiment. A high availability is also a key issue for the successful development of hydrotest projects. The AIRIX accelerator has been running for hydroshot experiments since 2000 and several thousands electron and X-ray beams have been produced. This paper outlines the reliability results of the AIRIX accelerator over a functioning period of ten years. Failure rates for each main subsystems are shown : injector, accelerating cells, high voltage generators, and measurement chains. We also give an overview of the most probable faults, with the associated occurrence rates, which can alter the X source of the AIRIX machine over this ten year period.
