在垂直于大半径方向用两个固定频率((?)0和(?)5GHz)的毫米波段外差接收机研究了在HL-1装置中等离子体的非热辐射。根据这些辐射与等离子体密度的关系,HL-1装置的放电可分为4种类型,并得到两个临界密度。这些辐射特性被认为是与逃逸放电性质和逃逸动力学不稳定现象有关。在实验中还观察到了与这种不稳定性有关的一系列等离子体宏观现象以及由此引起的逃逸损失。
The non-thermal radiation of the plasma in the HL-1 device was studied in a millimeter band heterodyne receiver perpendicular to the large radius with two fixed frequencies ((?) 0 and (?) 5GHz). According to these radiation and plasma density relationship, HL-1 device discharge can be divided into four types, and get two critical density. These radiation characteristics are believed to be related to the nature of escape discharge and the phenomenon of escape kinetic instability. A series of plasma macroscopic phenomena associated with this instability and the resulting escape losses were also observed in the experiments.
