| 摘 要： | 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。

| Abstract: | Non-thermal millimeter radiation from the plasma in the HL-1 device has been investigated at two fixed frequencies (80GHz and 35 GHz) by means of two superheterodyne receivers which are set up in a direction vertical to the major radius. In view of the relation between this radiation and the plasma density, discharges in HL-1 can be classified into four types. Two critical values of density are found. Runaway properties and phenomena pertaining to runaway kinetic instability are thought to be related to this radiation. A series of macroscopic phenomena and losses caused by the runaway kinetic instability are also investigated. |
