Beam transport and characterization on AIRIX prototype at CESTA

Designed to produce an X-ray dose of 500 rads @ 1m, AIRIX flash X-ray Radiographic facility will consist of 4 MeV/3.5 kA pulsed electron injector and 16 MeV induction accelerator powered by 32 H.V. generators. Construction of PIVAIR accelerator (8 MeV AIRIX prototype) is now ended at CESTA. The injector has been connected with 16 accelerating cells in order to study beam transport and centering procedures. Accurate, time resolved diagnostics have been used to measure beam characteristics and a tickler experiment has been planned to estimate BBU instabilities. In this paper all experimental data recently obtained is discussed and first conclusions for AIRIX are given.
