提出了等离子体产生和约束磁场的新概念，以提高低压下宽而密的离子束源的电子回旋共振（ECR）等离子体的效率。磁场结构由一对彼此相反极性的梳状磁体构成，并且其圆柱形地围绕等离子体室。这种磁性配置抑制了由于 E x B 漂移造成的损耗，从而增强了等离子体约束。使用 Langmuir 探针测量 2.45 GHz 和 11-13 GHz 微波的基波和二次谐波的 ECR 区域周围的电子温度和密度分布。在简单的多极和梳状磁性配置的各种操作条件下，它们的特性和效果都得到了阐明。
A new concept on magnetic field of plasma production and confinement has been proposed to enhance efficiency of an electron cyclotron resonance (ECR) plasma for broad and dense ion beam source under the low pressure. The magnetic field configuration is constructed by a pair of comb-shaped magnet which has opposite polarity to each other, and which cylindrically surrounds the plasma chamber. This magnetic configuration suppresses the loss due to E x B drift, and then plasma confinement is enhanced. The profiles of the electron temperature and density are measured around the ECR zones of the fundamentals and the second harmonics for 2.45 GHz and 11-13 GHz microwaves by using Langmuir probe. Their characteristics and effects are clarified under various operating conditions in both of simple multipole and comb-shaped magnetic configurations.
