Design parameters, goals, and status of the new ATLAS ECR ion source

A new 14 GHz ECR ion source for the ATLAS facility is under construction. The new source is an evolution of the 14 GHz AECR Lawrence Berkeley source. The new source will feature an all aluminum hexapole main chamber and enhanced peak radial and solenoid magnetic fields compared to the existing AECR. Most of the other design features of the existing source are maintained in this design. The new source will be mounted on a new 300 kV high voltage platform in order to match the velocity requirements of the existing PII injector linac. Achieving the very precise goal of a few electrical microamps of {sup 238}U{sup +33} from this source will allow the ATLAS facility to provide Coulomb-barrier energies of uranium without the use of an additional stripper foil and will significantly enhance the capabilities of ATLAS for the heaviest of beams. The project status and more details of the source system design are discussed.
