On this prototype RF measure- ments have been carried out. After low power conditioning in cw mode the structure was high power tested in pulsed mode. During the performance tests the 6 stem prototype was optimized and has shown the feasibility of a dipole free 4-rod RFQ at high frequencies and was testet up to 120 kW per meter. In this tests the input power and the electrode voltage was observed using gamma spectroskopy. From this the shunt impedance was calculated and compared to other methods of measurements. The power test results are presented in this paper.
