    "abstract": "The Low-Energy Demonstration Accelerator (LEDA) radio-frequency quadrupole\n(RFQ) is a 100% duty factor (CW) linac that delivers \u003e100 mA of H+ beam at 6.7\nMeV. The 8-m-long, 350-MHz RFQ structure accelerates a dc, 75-keV, 110-mA H+\nbeam from the LEDA injector with \u003e90% transmission. LEDA [1,2] consists of a\n75-keV proton injector, 6.7-MeV, 350-MHz CW RFQ with associated high-power and\nlow-level rf systems, a short high-energy beam transport (HEBT) and high-power\n(670-kW CW) beam stop. The beam emittance is inferred from wire scanner\nmeasurements of the beam profile at a single location in the HEBT. The beam\nprofile is measured as a function of the magnetic field gradient in one of the\nHEBT quadrupoles. As the gradient is changed the spot size passes through a\ntransverse waist. Measurements are presented for peak currents between 25 and\n100 mA.",
