Description
The Linac4 H⁻ ion source is a critical element of CERN’s operations, directly affecting both accelerator performance and its broad user base. As the sole injector particle source, its reliability and efficiency are essential to the stability of the entire proton accelerator chain and the physics programs it enables. This paper presents an overview of the system, drawing on six years of operational experience. It addresses key aspects including installation and maintenance strategies, spare parts management, the cesiation process, automated RF power regulation, as well as recent upgrades and improvements. Current performance metrics and availability figures are also discussed.
