摘要：

Neutral beams for the next generation tokamaks will be based on multiampere negative ion beams with a beam energy of about 1.0 MeV and pulse lengths of a thousand seconds. High intensity de beams at these levels of beam energy will require extensive development in electrostatic accelerators. At Lawrence Berkeley Laboratory, a two-module electrostatic quadrupole (ESQ) accelerator was built to accelerate ions to 260 keV. In this experiment, up to 100 mA of H- beam current was obtained from a Japan Atomic Energy Research Institute cesiated volume source using a multiaperture preaccelerator which merged 19 beamlets into a single circular beam at the entrance to the BSQ accelerator. The H- beam was accelerated by the ESQ to accelerate 200 keV without any significant beam loss or emittance growth. (C) 1995 American Institute of Physics.
