The first proton beam was extracted on September. In this paper we present the first set of measurements of protons transmission in combination with the analysis of the species (H⁺, H⁺₂, H⁺₃) extracted by the source. We show that our measurements are compatible with a fraction of 80\% of protons transported along the LEBT, as measured at the INFN-LNS, Catania, Italy during the commissioning in 2016-17.
