AIRIX prototype technological results at CESTA

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. 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 beam energy to 7.2 MeV. Two kinds of induction cells have been developed and tested. A focusing experiment is planned for electron beam spot diameter measurements. After this step, beam focusing on a target will be experimented for X-ray source characterization.
