Abstract
The results of modeling optimal scenario for electron cyclotron resonance (ECR) plasma heating in the GOL-NB multiple-mirror trap are presented. These results can serve as a basis for designing a system for auxiliary ECR plasma heating. Plasma heating by the extraordinary wave at the fundamental cyclotron harmonic of 70 GHz using microwave beam launched obliquely into the plasma from the high magnetic field side is demonstrated. A launching scheme is proposed that minimizes the influence of parasitic ECR in the vacuum chamber. For the basic magnetic configurations, the proposed scheme ensures ECR plasma heating with an absorption efficiency exceeding 90% in the range of on-axis plasma densities of \((0.1{-} 4.5) \times {10^{19}}\;{{\text{m}}^{ - {\text{3}}}}\) and an electron temperature of 20 eV. If performing special optimization, the density limit can be increased up to \(5.6 \times {10^{19}}\) m–3.
给出了电子回旋共振（ECR）等离子体在高尔-铌多镜阱中加热的最佳场景的模拟结果。这些结果可作为设计辅助ECR等离子体加热系统的基础。利用高磁场侧斜发射的微波波束，在70千兆赫的基波回旋谐波下加热等离子体。提出了一种减小真空室寄生ECR影响的启动方案。对于基本的磁结构，所提出的方案保证了ECR等离子体加热的吸收效率超过90% in the range of on-axis plasma densities of \((0.1{-} 4.5) \times {10^{19}}\;{{\text{m}}^{ - {\text{3}}}}\) and an electron temperature of 20 eV. If performing special optimization, the density limit can be increased up to \(5.6 \times {10^{19}}\) m–3.
