Recommissioning of the CERN Injector Complex Beam Instrumentation

During the last two years, the CERN injector complex has been completely renovated with the aim of providing high intensity and smaller emittance beams to the LHC. A new Linac providing H⁻ has been constructed and major upgrades in the Proton Synchrotrons (PS Booster ring, PS ring and Super PS ring) have been performed. A full suite of new beam diagnostics has been implemented and commissioned. This includes fast wire scanners, beam gas ionization monitors, quadrupolar pick-ups and diamond beam loss detectors. New radiation-hard beam position monitoring system was also successfully deployed in the SPS. This talk will present an overview of the performance of the newly built instruments.
