Abstract :
The ATLAS (Argonne Tandem Linear Accelerator System) Positive Ion Injector (PII) is designed to replace the tandem injector for the ATLAS heavy-ion facility. When the PII project is complete, ATLAS will be able to accelerate all ions through uranium to energies above the Coulomb barrier. PII consists of an ECR ion source on a 350-kV platform and a very-low-velocity superconducting linac. The linac is composed of an independently phased array of superconducting four-gap interdigital resonators which accelerate over a velocity range of 0.007 c to 0.05 c. The PII project is approximately 75% complete. Beam tests and experiments using the partially completed PII have demonstrated that the technical design goals are being met. The design, construction status, and results of recent operational experience using the PII are discussed.<>
