项目摘要

In the Low Aspect-ratio Torus Experiment (LATE) device, there observed a spontaneous formation of closed configuration of magnetic field when a electron cyclotron (EC) resonance plasma is produced under a weak vertical field superimposed on a toroidal field. A heavy ion beam probe (HIBP) system has been developed to measure the electrostatic potential which may play an important role on the transition of the magnetic topology. It is observed at the first time that the electrostatic potential is negative at -20 ~ -30V on the midplane near the EC resonance layer when the closed magnetic field configuration is formed. The result is completely different from the open field configuration case where the electrostatic potential is positive in the entire region. This result suggests that the electrostatic potential changes drastically through the transition from the open field configuration to the closed one.
在低纵横比环面实验(LATE)装置中,观察到在弱垂直场叠加环面场下产生电子回旋加速器(EC)共振等离子体时,会自发形成闭合磁场构型。研制了一种重离子束探针(HIBP)系统,用于测量在磁拓扑转变中起重要作用的静电势。第一次观察到,当形成闭合磁场构型时,在靠近EC谐振层的背板上-20 ~ -30V处静电电位为负。其结果与整个区域静电势为正的开场构型完全不同。这一结果表明,静电势在从开场形态到闭场形态的转变过程中发生了巨大的变化。
