The LEDA RFQ, a 350-MHz continuous wave (CW) radio-frequency quadrupole (RFQ), successfully accelerated a 100-mA CW proton beam from 75 keV to 6.7 MeV. We have accumulated 111 hr of beam on time with at least 90 mA of CW output beam current. The 8-mlong RFQ accelerates a dc, 75–keV, ~106-mA H beam from the LEDA injector with ~94% transmission. When operating the RFQ at the RF power level for wh...
