The ECR heavy-ion source for ATLAS

The ATLAS PII-ECR (electron cyclotron resonance) source is the first ECR ion source to be designed for operation on a high-voltage platform. The source system is required to provide beams of heavy ions with a velocity of 0.01 c for subsequent acceleration by the superconducting ATLAS Positive Ion Injector Linac. A beamline for atomic physics has been installed and is now in use. The ATLAS PII-ECR has demonstrated that high-charge-state ECR ion sources can be reliably operated in difficult environments such as high-voltage platforms. The source capabilities and operating experience to date are discussed.<>
