Radio Frequency Quadrupoles (RFQ) are modern tools to bunch and accelerate low energy ions as generated without modulation from ion sources at energies of sub 100 keV/u. RFQ manufacturing requires high precision machining by 5 axis mils, joining techniques keeping the tight tolerances of machining and a deep understanding of 3D rf modeling. With those capabilities in house RI expanded its activities in this demanding technology. The first 425 MHz system built for TechSource (final customer IUCF) with 5% duty cycle was delivered a few years ago.

Today we are in the final stage of the production of the GANIL RFQ operating in continuous mode at 88 MHz (see figure above) and started with design and production of the pulsed 402.5 MHz RFQ for the SNS project in Oak Ridge.

With those projects we cover a large span in frequency and duty cycle, all based on the four vane architecture. We expect further activities with this technology in the field of science and other applications. Our scope of supplies is completed by RF couplers, tuners pick-ups and other auxiliaries for all kind of normal conducting cavity applications.
