The ECR ion source at the TRIUMF isotope separator, TISOL

Abstract The installation at the isotope separator TISOL of a single staged ECR (electron cyclotron resonance) ion source has been completed. The source can now routinely deliver radioactive species extracted from the production target when bombarded by 500 MeV protons. Among the radioactive species detected so far are isotopes of He, C, N, O, Ne, Cl, Ar, Kr, and Xe including multiply charged states and with yields exceeding in some cases those of the ISOLDE facility at CERN. The effect of varying parameters on the operation of the source are discussed.
