Abstract :
AIRIX flash X-ray Radiographic facility is based on a 4 MeV- 3,5 kA pulsed electron injector and a 16 MeV induction accelerator. The accelerator will consist of 64 induction cells powered by 32 H.V. Pulsed generators operated at 250 kV. The final 20 MeV electron beam will be focused on a target designed for X-ray conversion. At CESTA, PIVAIR is a testbed designed as a validation step of AIRIX up to 8 MeV. The injector has been connected with 16 accelerating cells, increasing electron energy to 7.2 MeV. Two kinds of induction cells have been developed and tested. A focusing experiment has been performed for electron beam spot diameter measurements. PIVAIR is now currently used for beam focusing on a target, allowing X-ray source characterization and X-ray detector developments. The last technical improvements have been decided before beginning the induction cells and pulsed generators industrialization. AIRIX accelerator is now under construction: the 4 MeV injector has been commissioned and the first accelerating cells and pulse generators have been qualified at the rated voltage. A first beam test and characterization after 16 induction cells acceleration is planned by the end of 98 in order to validate industrial production
