AIRIX induction accelerator performances at CEA

AIRIX is an induction linear accelerator which is now operational for radiography in Commissariat a l´Energie Atomique in France. The accelerator consists in a 3.8 MeV-3 kA-60 ns injector and 64 induction cells powered by 32 high voltage generators. The energy of the beam at the end of the accelerator is 20 MeV. It has been designed to produce an X-Ray dose of hundreds of Rads at 1 meter with an X-Ray focal spot size of less than 2 mm. We present first a description of the different elements of the accelerator. We detail more especially the high voltage generators and their performances, which are necessary to have a good reproducibility of the beam at the end of the accelerator for each shot. In 1999, the acceptance tests were made with a 2 kA beam. At the beginning of 2001, we increased the current of the injector at 3.1 kA. We relate the first results of the performances of the machine with a 20 MeV-3.1 kA beam.
