IShTAR等离子体源的等离子体特性及螺旋模式的确认
Plasma characterization and confirmation of helicon mode of IShTAR plasma source
摘要：
离子回旋鞘层试验装置（Ion cyclotron Sheath Test Arrangement，ISHTAR）是位于德国加尔兴的马克斯-普朗克等离子体物理研究所的一个研究离子回旋射频（ICRF）波与等离子体相互作用的专用试验装置。等离子体由等离子体源（长度= 0.1 m，直径= 0.4 m）提供，负责在ICRF天线前创建必要的等离子体环境。该源配备有螺旋天线，并设计成达到放电模式。以前没有确认这种源可以达到螺旋放电模式。然而，重要的是这样的源，以达到螺旋放电模式，以其全容量工作，并产生高密度等离子体。为了实现螺旋放电模式的这种源进行了详细的研究。等离子体参数（即电子温度，密度和等离子体电位）的表征，然后由一个全球性的粒子和功率平衡模型的实施已经取得。在较低的磁场（B <35 mT）下证实了螺旋模的存在。为了获得尽可能高的等离子体密度，提出了等离子体源的优化，以在最高可用磁场下达到螺旋模式。
英文摘要：
IShTAR (Ion cyclotron Sheath Test ARrangement) is a dedicated test facility to investigate the interaction of ICRF wave and plasma at the Max-Planck Institute for Plasma Physics in Garching, Germany. Plasma is provided by a plasma source (length= 0.1m, diameter = 0.4m) and it is responsible to create the necessary plasma environment in front of the ICRF antenna. The source is equipped with a helical antenna and designed to reach the mode of discharge. Previously there was no confirmation that this source can reach helicon mode of discharge. However, it is important for such a source to reach the helicon mode of discharge to work with its full capacity and to produce high-density plasma. To achieve helicon mode of discharge for this source a detailed study was carried out. Characterization of plasma parameters (i.e. electron temperature, density, and plasma potential) followed by the implementation of a global model of particle and power balance has been made. The existence of helicon mode confirmed at lower magnetic fields (B <35 mT). To get the highest possible plasma density, the optimization of the plasma source is presented to reach helicon mode at the highest available magnetic field.
