Abstract :
We report preliminary test results for a 6.7-MeV, 100-mA cw radio-frequency quadrupole. During the time this structure was in design, fabrication, assembly, tuning, and installation, we tested a 75-keV proton injector, 350-MHz high-power RF systems, EPICS controls, diagnostics, beam stop, and other hardware in preparation for the 670 kW beam test. Initial LEDA RFQ beam operation has commenced. This paper summarizes work in the past year, concentrating on RFQ assembly, tuning, installation, high-power conditioning and initial beam operation. We include summaries of injector tests, 1.25-MeV RFQ-beam tests, beam-transport and beam-stop performance, and cavity resonance control. The technology being developed in this first section of the APT (accelerator production of tritium) linac is also appropriate for several other applications, including the transmutation of waste and medical isotope production
