Two single-stage, 6 GHz electron cyclotron resonance (ECR) ion sources are currently in use at the ARENAS project at Louvain-1a-Neuve. One of them is used to ionize radioactive elements to low charge states (1(+) to 4(+)) before injection in the postaccelerator cyclotron. High intensity beams of He-6, C-11, N-13, Ne-18, and Ne-19 are being produced. Recently the source has been adapted for the ionization of F-18 and the first experiment with this beam has been performed. A second ECR source, almost identical to the first, is used in combination with the Leuven isotope separator on-line. It produces stable and radioactive beams at 50*q keV. Mass separated beams of N-13, O-14, and O-15 can be produced using a high-temperature carbon target. An upgrade of this type of ECR source is now under construction. It consists mainly of increased magnetic fields and the capability for insertion of a heated cavity. (C) 1996 American Institute of Physics.
