| 内容記述 | tFor the IFMIF/EVEDA accelerator prototype RFQ linac, a 175 MHz rf input coupler based on a 6 1/8 in. co-axial waveguide is designed and manufactured. The rf coupler has cooling channels into the loop antennaand inner/outer-conductors around the RF window for CW operation mode, and the rf vacuum windowmodule is replaceable by flanged connection. For rf power capability, nominal rf power of 160 kW andmaximum transmitted rf power of 200 kW are required. In order to test the rf power capability, rf powertests using a high-voltage standing waves on a high-Q load circuit are carried out. For manufactured ninerf couplers including one spare, a stable 14 s CW operation at the equivalent rf power of 200 kW wereachieved within 3–5 days rf aging. No rf contact defects, no unnecessary low-Q value and no extraordinaryoutgassing were validated. | |||||
