Beam performance achievements in the CERN accelerator complex in the LIU era:
The CERN injector complex underwent significant changes under the LHC Injectors Upgrade (LIU) project during Long Shutdown 2 (LS2). The primary goal of the LIU project was to prepare the complex for the High Luminosity LHC (HL-LHC) era, with a particular focus on extending the brightness reach of the beams. Beyond this core objective, the upgrades have delivered broad benefits across the entire CERN accelerator complex, enhancing overall operational performance. Following the conclusion of one of the most successful runs in the injectors, this contribution reviews the key beam performance achievements across the CERN accelerator complex during Run 3. It highlights the most important lessons learnt and outlines the strategy for restarting the machines for the start of the HL-LHC operation.
