A comprehensive diagnostic suite for field-reversed configuration (FRC) plasmas has been developed and installed on the C-2 device at Tri Alpha Energy to investigate the dynamics of FRC formation as well as to understand key FRC physics properties, e.g., confinement and stability, throughout a discharge. C-2 is a unique, large compact-toroid merging device that produces FRC plasmas partially sustained for up to ∼5 ms by neutral-beam (NB) injection and end-on plasma-guns for stability control. Fundamental C-2 FRC properties are diagnosed by magnetics, interferometry, Thomson scattering, spectroscopy, bolometry, reflectometry, and NB-related fast-ion/neutral diagnostics. These diagnostics (totaling >50 systems) are essential to support the primary goal of developing a deep understanding of NB-driven FRCs.
一套用于场反转配置（FRC）等离子体的综合诊断设备已被研发并安装在Tri Alpha Energy公司的C-2装置上，以研究FRC形成的动力学过程，并了解整个放电过程中FRC的关键物理特性，例如约束和稳定性。C-2是一种独特的大型紧凑型环形合并装置，通过中性束（NB）注入和用于稳定性控制的端对端等离子体枪产生部分持续长达约5毫秒的FRC等离子体。通过磁学、干涉测量、汤姆逊散射、光谱学、测热辐射计、反射测量以及与NB相关的快离子/中性诊断来诊断C-2 FRC的基本特性。这些诊断设备（总数超过50个系统）对于支持深入理解NB驱动的FRC这一主要目标至关重要。
