论文摘要
ISHTAR（离子回旋鞘测试排列）是一个专门的测试设施，用于研究德国Garching的Max-Planck血浆物理学研究所在Max-Planck血浆物理学研究所的相互作用。血浆由等离子体源（长度= 0.1m，直径= 0.4M）提供，并且负责在ICRF天线前创建必要的等离子体环境。该源配备了螺旋天线，并设计为达到排放方式。以前没有确认该来源可以达到Helicon的排放方式。但是，对于这样的来源而言，要达到Helicon的排放模式以便其全容量并产生高密度等离子体，这一点很重要。为了实现此源的直升机排放方式，进行了详细的研究。已经制定了等离子体参数（即电子温度，密度和等离子体电位）的表征，然后实现了粒子和功率平衡的全局模型。在较低的磁场（b <35 mt）上证实了Helicon模式的存在。为了获得最高的血浆密度，在最高可用的磁场上提出了等离子体源的优化以达到Helicon模式。
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.
