002824415 520__ $$9Physical Society of Japan$$aThe LHC Injector Upgrade (LIU) was launched in 2010 in synergy with the High Luminosity LHC (HL-LHC) project.^2) It includes the consolidation/upgrade of the PS Booster RF systems:^3,4) all the existing ferrite-loaded RF cavities are being replaced with wideband RF systems during the 2019–2020 long shut down. The magnetic-annealed cores improve the cavity performance and reduce the number of the straight sections for RF systems. In 2013, during the first long shut down of the LHC, LS1, we performed a beam loading test in J-PARC using a one-cell type Booster cavity. The beam test using a high intensity beam proved that direct-feedback can work in conjunction with the other beam loading compensation system.^5) J-PARC also cooperates on the R&D; of a Rad-Hard solid-state amplifier. A recent irradiation test shows that the amplifier can withstand up to 2 kGy under mixed field irradiation.^6) J-PARC contributions for the LIU project will be reported.
