The large number of different experiments performed at the 88-Inch Cyclotron requires great
variety and flexibility in the production of ion beams. This flexibility is provided by the two high
performance ECR ion sources, the LBL ECR and the AECR-U, which can produce beams of ions
as light as hydrogen and as heavy as uranium. With these two sources up to six different metals
can be preloaded using two types of ovens. The ovens are mounted radially on the ion sources and
inject the metal vapor through the open sextupole structure into the plasma chamber. For the
superconducting ECR ion source VENUS, which is under construction at LBNL, the use of radial
ovens is no longer possible, because the magnetic structure is closed radially. Therefore, we are
developing two new axial oven types for low and high temperature applications.
Metal ion beam production in ECR ion sources using the oven technique is discussed. The design
of the axial oven is presented. Finally the efficiency of the axial oven is compared with the radial
oven for the production of Ca.
