Abstract

In this Letter, results of measurements of radiation losses P_rad and effective ion charge Z_eff in the conditions of magnetic field up to 0.7 T and plasma current up to 300 kA for a wide range of electron density first obtained on the Globus-M2 tokamak are presented. The analysis of the results shows the decrease in the radiation losses share of the input power on the Globus-M2 tokamak as compared with the same parameter for the Globus-M facility. A large dip at the center of the P_rad power profiles is revealed. A decrease in the Z_eff values is observed with an increase in electron density.

Globus-M2托卡马克上的辐射损失和有效离子电荷的测量

摘要

在这封信中，首次在Globus-M2托卡马克上获得的宽电子密度下，在高达0.7 T的磁场和高达300 kA的等离子体电流条件下的辐射损耗P _rad和有效离子电荷Z _eff的测量结果被提出。结果分析表明，与Globus-M设施的相同参数相比，Globus-M2托卡马克上输入功率的辐射损耗份额降低了。显示了P _rad功率曲线中心的大倾角。随着电子密度的增加，观察到Z _eff值的降低。
