The Linac4 H⁻ ion source plays a vital role for the CERN operation and experimental users. Its performance and availability have a direct and critical impact on the CERN's proton accelerator chain and the physics programs it supports. This paper presents an overview of the system, the operational experience and the lessons learned during the full five years of official running. Key topics as...
The world's first Nb3Sn and NbTi superconducting electron cyclotron resonance (ECR) ion source, FCER (First 4th-generation ECR ion source), has been deployed in the LEAF (Low Energy high-intensity heavy ion Accelerator Facility) project in 2024. Following initial tuning, under 28+45 GHz microwave heating, the FCER successfully produced 350 eμA of Bi35+ and 620 eμA of Bi31+ ion beams. Recently,...
