  Linac4, the new CERN H− in­jec­tor to the Pro­ton Syn­chro­tron Booster, has been com­mis­sioned and has de­liv­ered a beam in­ten­sity and qual­ity cal­cu­lated to be suf­fi­cient to pro­duce the stan­dard beams for LHC and the high in­ten­sity beams for ISOLDE when con­nected. The beam cur­rent is nev­er­the­less half of what is fore­seen and the prob­lem has been iden­ti­fied at the low en­ergy end, be­tween the ex­trac­tion and the match­ing to the RFQ. The Linac4 test stand is being used to ad­dress this issue by test­ing dif­fer­ent ex­trac­tion geome­tries and dif­fer­ent plasma gen­er­a­tors. A fast method to ac­cess the cur­rent in the RFQ ac­cep­tance has been put in place. This paper re­ports the re­sults of the mea­sure­ments ob­tained so far.
