Linac4 is a 160 MeV H- linear accelerator presently
under construction at CERN. It will replace the present
50 MeV proton Linac2 as in jector of the proton accelera-
tor complex as part of a project to increase the LHC lumi-
nosity. The Linac4 front-end,composed of a 45 keV ion
source, a Low Energy Beam Transport (LEBT), a
352.2 MHz Radio Frequency Quadrupole (RFQ) which
accelerates the beam to 3 MeV and a Medium Energy
Beam Transport (MEBT) housing a beam chopper, has
been commissioned in the Linac4 tunnel. The MEBT is
composed of three RF cavities and 11 quadrupole mag-
nets to match the beam from the RFQ to the next acceler-ating structure (DTL) and it includes two wire scanners for beam profile measurement. In this paper we present the results of the profile me asurements and we compare them with emittance measurements taken with a tempo-rary slit-and-grid emittance measurement device located after the MEBT line.
