Abstract :
A 2.45 GHz electron cyclotron resonance (ECT) ion source, recently developed at Chalk River, a was installed on the RFQ1 (radiofrequency quadrupole-1) facility for comparison with the duoPIGatron source used previously. The proton fraction of the ECR ion source is 80 to 85% much higher than the 30 to 35% of the duoPIGatron. Measurements of the beam transmission through the RFQ, as well as the emittance of the extracted and the accelerated beams, are reported. Four-aperture extraction columns were used on both sources.<>
