| Abstract: | A direct plasma injection scheme (DPIS) project has been developed since 2007 at the Institute of Modern Physics, Chinese Academy of Sciences (IMP, CAS). In this paper, the test methods and results of radio frequency (RF) characteristics are presented, and especially a new approach, which can calibrate a directional coupler by the RF instrument, is introduced to measure the pulsed power precisely. Furthermore, we present the conditioning situation of the whole radio frequency quadrupole (RFQ) system including the analysis of and the solutions to the sparking of the cavity and amplifier. Finally, the result from the beam experiment proves that the design and measurement can meet the commissioning demand. |
