Abstract :
The 0-mode RFQ consists of 4 trapezoidally modulated electrodes, manufactured on a lathe and periodically supported by radial stems. This resonator is excited in ¿-0-mode forming an RFQ field, which is highly stable against tolerances and dipole-modes. A compact proton accelerator (10 - 300 keV, 108 MHz) with high duty cycle has been built and RF properties and first beam measurements are presented. New sparking experiments and results of high power tests with a 18 MHz spiral-RFQ are discussed.
