Abstract :
For the 7 MeV proton linac at the Institute for Chemical Research (ICR), Kyoto University, Japan, improvement of beam transmission has been made. The measurement of the RFQ output beam was performed and the beam matching elements were designed and constructed to match the RFQ output beam to the acceptance of the Alvarez linac. The emittance is 42 π·m·mrad and 30 π·m·mrad in the x-x´ plane and y-y´ plane, respectively. The energy spread is 80 keV at 2 MeV. The matching elements consist of four permanent magnetic quadrupoles and a quarter wave-length resonator buncher. RF power up to 5 kW has been safely fed into the buncher, which is good enough to provide a designed bunching voltage of 180 kV
