为研究与空间、天体物理及聚变等离子体相关的多X线区域中的磁重联，实验室重联实验装置（FLARE）已建成。基于磁重联实验装置（MRX）的成功设计，FLARE具有更大的物理体积、更强的磁场以及独立的欧姆加热驱动，可显著扩展可及参数空间，目标是达到 Lundquist数S~10^5，归一化系统尺寸λ~10^3。本文详细介绍该装置的核心工程组件，包括主真空室、内部通量芯、高度分段的外部线圈系统、模块化电容器组以及安全联锁与控制架构。还介绍了初始诊断套件，包含高分辨率二维磁探针阵列、三探针朗缪尔探针、全光纤耦合干涉仪、离子多普勒光谱仪和快速相机成像。初始运行结果表明该装置具有实验灵活性和可靠性，成功实现了对称推拉式重联、球形托卡马克合并以及非对称下游构型。目前FLARE处于“2.5阶段”，在反平行重联中S~2500、λ~60，可立即进入多X线区域。计划中的硬件升级、先进诊断添加以及与全动理学模拟的集成，将进一步扩展其能力，使其过渡为面向更广泛等离子体科学领域的合作用户装置。
英文摘要
The Facility for Laboratory Reconnection Experiments (FLARE) has been constructed to study magnetic reconnection in multiple X-line regimes relevant to space, astrophysical, and fusion plasmas. Building upon the successful design of the Magnetic Reconnection Experiment (MRX), FLARE features a larger physical volume, stronger magnetic fields, and an independent ohmic heating drive to significantly extend the accessible parameter space, targeting Lundquist numbers up to S ~ 10^5 and normalized system sizes up to λ~ 10^3. This paper details the facility's core engineering components, including the primary vacuum vessel, internal flux cores, highly segmented external coil systems, modular capacitor banks, and the safety interlock and control architecture. An initial diagnostic suite is presented, comprising high-resolution 2D magnetic probe arrays, triple Langmuir probes, a fully fiber-coupled interferometer, ion Doppler spectroscopy, and fast camera imaging. Initial operations demonstrate the device's experimental flexibility and reliability, successfully executing symmetric push-pull reconnection, spheromak merging, and asymmetric downstream configurations. Currently operating within "Stage 2.5" with S ~ 2,500 and λ~ 60 for anti-parallel reconnection, FLARE provides immediate access to the multiple X-line regimes. Planned hardware upgrades, advanced diagnostic additions, and integration with fully kinetic simulations will further expand its capabilities as it transitions into a collaborative user facility for the broader plasma science community.
