Abstract:
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.
