The 75-keV injector and 6.7-MeV RFQ that comprise the first portion of the cw, 100-mA proton linac for the accelerator production of tritium (APT) project have been built and tested. The LEDA RFQ has been extensively tested for pulsed and cw output-beam currents {le} 100-mA. Up to 2.2 MW of cw rf power from the 350-MHz rf system is coupled into the RFQ, including 670 kW for the cw proton beam. The RFQ output beam emittance for a 93-mA pulsed RFQ output beam, determined from quadrupole-magnet-scan measurements, is {var_epsilon}{sub x} x {var_epsilon}{sub y} = 0.25 x 0.31 ({pi} mm mrad){sup 2} [rms normalized]. A follow-on experiment, to intentionally introduce and measure beam halo on the RFQ output beam, is now being installed.
