    "abstract": "Recently, the Low-Energy Demonstration Accelerator (LEDA) portion of the\nAccelerator Production of Tritium (APT) project reached its 100-mA, 8-hr CW\nbeam operation milestone. LEDA consists of a 75-keV proton injector, 6.7-MeV,\n350-MHz CW radio-frequency quadrupole (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 dump. During the commissioning phase it was discovered that\nthe RFQ field level must to be approximately 5-10% higher than design in order\nto accelerate the full 100-mA beam with low losses. Measurements of a\nlow-duty-factor, 100-mA beam show the beam transmission is unexpectedly low for\nRFQ field levels between ~90 and 105% of design. This paper will describe some\naspects of LEDA operations critical to achieving the above milestone.\nMeasurement and simulation results for reduced RFQ beam transmission near\ndesign operating conditions are also presented.",
