在紧凑螺旋系统 (CHS) 中的切向中性束注入 (NBI) 加热过程中,经常会在多个诊断信号中检测到锯齿振荡 [K. Matsuoka 等人,等离子体物理学和受控核聚变研究,1988 年(国际原子能机构,维也纳,1989 年),第 1 卷。 2,第 14 页。 441]。锯齿形碰撞与位于归一化小半径ρ∼0.5上的q=2(q为安全系数)有理面密切相关,并且大多数碰撞都具有环形碰撞的特征。磁轴上等离子体参数的扰动取决于环形等离子体β和q=2表面的尺寸。碰撞的时间尺度相当大,达到 0.5-1.0 毫秒,比托卡马克的时间尺度大一个数量级。 m/n=2/1(m和n分别是极向和环形模式数)的两种类型的磁波动,即鱼骨状突发模式(FB)和低频理想/电阻交换模式(LF模式),在碰撞之前增长。那些内...
Sawtooth oscillations are often detected in the signals of several diagnostics during tangential neutral beam injection (NBI) heating in the compact helical system (CHS) [K. Matsuoka et al., Plasma Pysics and Controlled Nuclear Fusion Research, 1988 (International Atomic Energy Agency, Vienna, 1989), Vol. 2, p. 441]. The sawtooth crashes are closely related to the q=2 (q is the safety factor) rational surface located on the normalized minor radius ρ∼0.5 and most of the crashes indicate a character of an annular crash. The disturbance of plasma parameters on the magnetic axis depends on the toroidal plasma beta and the size of the q=2 surface. The time scale of the crash is fairly large to be 0.5–1.0 ms which is an order of magnitude larger than that in tokamaks. Two types of m/n=2/1 (m and n are poloidal and toroidal mode numbers, respectively) magnetic fluctuations, which are fishbone-like burst mode (FB) and low frequency ideal/resistive interchange mode (LF mode), grow just before the crash. Those inte...
