Abstract

A long-lived field-reversed configuration (FRC) plasma has been produced in the C-2 device by dynamically colliding and merging two oppositely directed, highly supersonic compact toroids (CTs). The reversed-field structure of the translated CTs and final merged-FRC state have been directly verified by probing the internal magnetic field structure using a multi-channel magnetic probe array near the midplane of the C-2 confinement chamber. Each of the two translated CTs exhibits significant toroidal fields (B(t)) with opposite helicity, and a relatively large B(t) remains inside the separatrix after merging.

摘要

在C-2装置中，通过使两个方向相反、高度超音速的紧凑环向等离子体（CT）动态碰撞并合并，产生了一种长寿命的场反向配置（FRC）等离子体。通过使用C-2约束腔室中平面附近的多通道磁探针阵列探测内部磁场结构，直接验证了平移后的CT的反向场结构和最终合并的FRC状态。两个平移后的CT中的每一个都表现出具有相反螺旋性的显著环形磁场（B(t)），并且合并后在磁分界面内仍保留有相对较大的B(t)。
