	TIME Co. developed a new 4-vane RFQ structure that can be used for a very high-duty factor operation. We eliminated the tuners to flatten the field distribution. The tuners increase RF contacts which may trigger unex-pected local heat spots and subsequent discharges. In addition, we hollowed out the entire vane to achieve large cooling water channels. A high-power test showed that the commissioning was completed within one day. We could input a nominal RF power without experienc-ing almost any discharge. The applied duty factor was 5 % at the 200 MHz resonant frequency, and the meas-ured frequency shift was not detected. These activities have been carried out in collaboration with Tokyo Institute of Technology and RIKEN.
