A new 14 GHz ECR ion source for the ATLAS facility is under constructi
on. The new source is an evolution of the 14 GHz AECR Lawrence Berkele
y source. The new source will feature an all-aluminum hexapole main ch
amber and enhanced peak radial and solenoid magnetic fields compared t
o 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 r
equirements of the existing PII injector linac. Achieving the very pre
cise goal of a few electrical microamps of U-238(+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 signif
icantly enhance the capabilities of ATLAS for the heaviest of beams. T
he project status and more details of the source system design are dis
cussed. (C) 1996 American Institute of Physics.
