	AIRIX is a linear accelerator dedicated to X-ray flash radiography at CEA's hydrotest facility. It has been designed to generate an intense X-ray pulse using a 2 kA, 19 MeV and 60 ns electron beam. The electron beam transport in the accelerator is insured by the knowledge of the dynamic and dimensional characteristics of the beam created downstream the injector. These characteristics are assessed from a measurement chain, established by adapted optics and an intensified camera, aiming at observing the Cerenkov radiation produced during the interaction of electrons with a mylar target placed in the beam. This paper deals with the characterization, and comparison with the previous model, of a new intensified camera which was experimentally tested on AIRIX during an injector characterization campaign. This allowed defining profile and emittance beam characteristics. The obtained results are promising and revealed very interesting properties in particular in term of dynamic, temporal resolution, linearity and signal-to-noise ratio.
