Linac4, the future 160 MeV H-injector to the CERN
Proton Synchrotron Booster, is presently under
construction at CERN as a central step of the planned
upgrade of the LHC injectors. The Linac front-end,
composed of a 45 keV ion source, a Low Energy Beam
Transport (LEBT), a 352.2 MHz Radio Frequency
Quadrupole (RFQ) and a Medium Energy Beam
Transport (MEBT) housing a beam chopper, has been
installed and commissioned. Precise measurements of the
longitudinal micro bunch profiles of ion beams were
possible with the help of a Bunch Shape Monitor (BSM)
developed at INR Moscow. These were crucial for the
successful commissioning of the three RF buncher
cavities mounted along the MEBT and well
complemented with higher precision the information
provided in parallel by spectrometer measurements
