Query: LEDA Beam Operations Milestone and Observed Beam Transmission
  Characteristics   Recently, the Low-Energy Demonstration Accelerator (LEDA) portion of the
Accelerator Production of Tritium (APT) project reached its 100-mA, 8-hr CW
beam operation milestone. LEDA consists of a 75-keV proton injector, 6.7-MeV,
350-MHz CW radio-frequency quadrupole (RFQ) with associated high-power and
low-level rf systems, a short high-energy beam transport (HEBT) and high-power
(670-kW CW) beam dump. During the commissioning phase it was discovered that
the RFQ field level must to be approximately 5-10% higher than design in order
to accelerate the full 100-mA beam with low losses. Measurements of a
low-duty-factor, 100-mA beam show the beam transmission is unexpectedly low for
RFQ field levels between ~90 and 105% of design. This paper will describe some
aspects of LEDA operations critical to achieving the above milestone.
Measurement and simulation results for reduced RFQ beam transmission near
design operating conditions are also presented.
