Magnetic Waveform Measurements of the PSB Extraction Kicker KFA14L1 and Future LIU Emittance Growth Estimates

Understanding the different sources of emittance dilution along the LHC injector chain is an import-ant part of providing the high brightness proton beams demanded by the LHC Injectors Upgrade (LIU) project. In this context, the first beam-based measurements of the magnetic waveforms of the Proton Synchrotron Booster’s (PSB) extraction kickers were carried out and used to quantifythe transverse emittance blow-up during extraction and transfer to the Proton Synchrotron (PS).In this report, the waveform measurement technique will be briefly outlined before the results andtheir implications for the LIU project and beam performance reach are discussed.
