The PHIL (PhotoInjector at LAL: http://phil.lal.in2p3.fr/ ) accelerator is the new LAL (Orsay, France) facility dedicated to test state-of-the-art RF and beam sources technologies used for future electron accelerators. The machine based on 3 GHz RF gun triggered with a 262 nm wavelength laser, delivers a low energy ( E<10 MeV) single pulse electron beam at 5 Hz, with a low charge (0.1 nC) for now. The machine is about 5 meters long, with one direct and one deviated beam line (created after a 60° dipole). This paper describes the current status (first beam in november 2009) and the development of the diagnostics sections of the machine. At present, the machine is equipped by a transverse beam profile monitor based on «YAG:Ce» screen (30 mm diameter and 300 micrometers thick), two BPMs (one "button type" and one "reentrant resonators" type) and two Faraday cups (at the end of each line). The paper will present some preliminary results of the dimension and position of the beam at specific point for different charges and phase, and will present the expected development of the diagnostics of the machine (measurement of mean and energy dispersion, 2D emittance, beam length).
