	Funding: The work is supported by Federal Targeted Program "Scientific and Scientific-Pedagogical Personnel of the Innovative Russia in 2009-2013" (Governmental Contract no. p 793) In this paper we discuss some problems of modeling of beam slow extraction systems. It is known that similar type of beam extraction is used for different kind of circular accelerators. Among the most important requirements for such systems is necessary to mention the time uniformity of the extracted beam. There exist the following two key causes. The first of them is induced by time discontinuity of the corresponding steering electrical currents, and the second cause is induced by an beam inertia which usually connected with beam feedback mechanism, which is usually used for temporal smoothing of the corresponding magnetic (and electrical) fields. In the base of our approach we put the matrix formalism for Lie algebraic tools, which allows us to analyze different kind of the time discontinuity cause.

	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.
