Description
In this report, we present a comprehensive redesign of the CLIC main beam injector complex for the 380 GeV energy stage. The main beam injector complex generates and accelerates electrons and positrons to 9 GeV at the end of the booster linac. Benefiting from the improved positron yield, the electron drive beam energy for positron production is reduced from 5 GeV to 2.86 GeV, and the electron and positron injector linacs are redesigned to achieve a more compact layout of the injector complex, with the total length reduced by a factor of two. Jitter amplification due to short-range and long-range wakefields are studied for the injector and booster linacs.
