THE UOFA TRIUMF RADIOACTIVE BEAM ECR ION-SOURCE

One of the objectives of the TISOL (Test Isotope Separator On Line) facility at TRIUMF is the production of low Z radioactive isotopes, with a special interest in those related to nuclear astrophysics. A part of experimental objectives is the installation of an electron cyclotron resonance ion source on-line to test its suitability for this use. In collaboration with TISOL, the University of Alberta has designed, built, and tested off-line a single stage ECRIS. As part of the source, testing measurements were carried out to determine the efficiency of the source; some preliminary results indicate efficiencies of 20% for Ne+ and 30% for Ar+. In general, it was attempted to test the source under as wide as possible a set of operating conditions. The final off-line testing is completed. It is hoped that the source will go on-line in the early summer of 1989.
