Development work with solid materials at the Argonne National Laboratory ECR ion sources has been focused on two areas-introduction of materials with low vapour pressures,and increasing the beam intensities of heavy beams(i.e.-lead and uranium).An induction oven,with a demonstrated operating temperature extending to 2000℃,has been utilized to produce a Ti-50 beam with an intensity of 5.5eμA (12+).In addition,a refinement of the sputter technique has been employed which has resulted in a 42% improvement in lead beam intensities.Details of the induction oven as well as the refined sputter technique will be presented.
