Beam Position Monitor System for the CERN LINAC4

The new LINAC4 will provide 160 MeV H- ion beams for charge-exchange and proton injection into the CERN accelerator complex. Among a wide variety of beam diagnostics devices, shorted stripline pick-ups will measure the absolute beam position, the relative and absolute beam current, and the average beam energy via the time-of-flight between two monitors. This paper describes the beam position monitor (BPM) with its electronic acquisition chain to be implemented on the movable test bench for beam characterization up to 12 MeV.
