Zhu, K. JACoW Publishing Geneva, Switzerland A window-type RFQ is designed and fabricated by Peking University. It is planed to accelerate 50mA deuteron cw beam to 1MeV. The 60kV intervane voltage is designed to decrease the risk of high voltage discharge since the RFQ works in cw mode. High power test shows that the intervane voltage is over 60kV when the Cavity power consumption is 48kW. The beam experiment was done and 1.8mA cw beam was obtained at exit of RFQ with over 90% transmission efficiency. This paper will present the cold model measurement, high power RF conditioning and beam experiment result.
