用Langmuir探针在降低等离子体电流下对托卡马克核心区进行了研究。测量密度和温度分布。给出了观测到的类漂波不稳定性的检测频率和速度的结果，并与系统中测量的密度梯度得到的相应值进行了比较。在核心区检测到的等离子体环面旋转归因于在该区域观测到的频率（从理论值）的移位。用Langmuir探针测量了局部粒子通量，并与混合长度近似的测量结果进行了比较
The tokamak core region has been investigated by using Langmuir probes at reduced plasma currents. Density and temperature profiles are measured. The results on the detected frequencies and velocities of the observed drift-wave-like instabilities are presented and compared with the corresponding values obtained from the density gradient measured in the system. Plasma toroidal rotation detected in the core region is attributed to the shift in frequency (from theoretical values) observed in that region. The local particle flux has also been measured with Langmuir probes and compared with the measurements from the mixing length approximation
