论文摘要
射频（RF）驱动的Helicon等离子体源通常用于在相对中等的功率（典型的RF功率<2 kW）下产生高密度氩等离子体（N> 10^19/m^3）的能力。典型的电子温度<10 eV，典型的离子温度<0.6 eV。新设计的Helicon天线组件（带有同心，双层，完全冷却的RF-Transparent Windows）在稳态的RF Powers中运行，最高为10 kW。我们报告氩血浆密度，电子温度和离子温度对RF功率的依赖性。在10 kW时，用激光诱导的荧光测量了氩等离子体中的离子温度> 2 eV，这与简单体积平均的0-D功率平衡模型一致。这些血浆条件的中性密度谱图的1-D蒙特卡洛模拟在核心附近显示出强中性耗竭，并预测中性温度远高于室温。在此高功率直升机源中产生的等离子体（当使用光离子时）非常适合中性束的融合移移等离子材料相互作用研究和负离子产生。
Radio Frequency (RF) driven helicon plasma sources are commonly used for their ability to produce high-density argon plasmas (n > 10^19/m^3) at relatively moderate powers (typical RF power < 2 kW). Typical electron temperatures are < 10 eV and typical ion temperatures are < 0.6 eV. A newly designed helicon antenna assembly (with concentric, double-layered, fully liquid-cooled RF-transparent windows) operates in steady-state at RF powers up to 10 kW. We report on the dependence of argon plasma density, electron temperature and ion temperature on RF power. At 10 kW, ion temperatures > 2 eV in argon plasmas are measured with laser induced fluorescence, which is consistent with a simple volume averaged 0-D power balance model. 1-D Monte Carlo simulations of the neutral density profile for these plasma conditions show strong neutral depletion near the core and predict neutral temperatures well above room temperatures. The plasmas created in this high-power helicon source (when light ions are employed) are ideally suited for fusion divertor plasma-material interaction studies and negative ion production for neutral beams.
