摘要：
A multi-ring-cusp-type surface magnetic field is tested for production of large-diameter electron cyclotron resonance (ECR) plasma. The density and its distribution are improved by means of a new launching system consisting of an adjustable antenna and a microwave suppressor inserted into the vacuum chamber, which forces the microwave to propagate into the plasma from the stronger side of the surface magnetic fields.
