The injector system of SOLEIL is composed of a 100 MeV electron linac pre-accelerator followed by a full energy 2.75 GeV booster synchrotron, operating at 3 Hz. Dedicated diagnostics such as emittance monitors are installed on the two transfer lines between the linac and the booster and between the booster and the storage ring. The measurement is performed using the gradient method, relying on YAG screens and high resolution CCD cameras. This paper will show the metrology of the emittance measurements which were made for the HELIOS (THALES) iinac beam (total emittance in the range of 1 μm.rad) and for the booster beam (rms emittance ~ 150 nm.rad): error sources are identified and specific corrections are shown. Additional analysis of the dynamics of the injection into the booster and into the storage ring is made for a deeper characterization.
