托卡马克芯区Z_(eff)测量和分析方法的研究

Study on the measurement and analysis of Z_(eff) in the core of tokamak discharges

基于等离子体锯齿弛豫振荡的测量和研究,结合芯区电子功率平衡的分析,获得一种可靠的确定芯区平均有效离子电荷数Zeff的测量方法。该方法不受杂质的限制,测量条件十分容易满足。

The mean effective ion charge Z_(eff) in the core of ohmic tokamak discharge has been determined from information on sawtooth-relaxations of the steady state plasma,using an analysis of the power balance of the plasma electrons in the plasma core.This method is simple and fast to supply trustworthy results for the tokamak discharge.
