Abstract :
The Chalk River RFQ1 accelerator was built with replaceable vanes, and a new set of vanes was designed. The vanes fabricated are identified as RFQ1-1250, while the original vanes are identified as RFQ1-600. The RFQ1-600 vanes were designed with a peak surface electric field of 1.5 times Kilpatrick, which is now viewed as being too conservative. The new design used a peak field of 1.8 Kilpatrick and a modified tip profile to increase the output energy from 0.6 MeV to 1.25 MeV. The vanes have been machined out of GlidCorp AL-15 (an alumina dispersion-strengthened copper) with the cooling channels gun drilled. Details of the fabrication (including details of the tip profile cutting), installation, and tuning are described.<>
