Equilibrium reconstruction is the essential diagnostic tool for determining the magnetic field and current density of a tokamak discharge. This method parametrizes the unknown current profile with a suitable set of test functions and determines the coefficients from measurements. For steady state discharges, a continuous equilibrium analysis is required. The purpose of the Tore Supra CIEL project is the study of discharges with duration up to 1000 s. We report on the development of a real-time version of the widely used equilibrium code EFIT.
平衡重建是确定托卡马克放电中磁场和电流密度的基本诊断工具。该方法利用一组适当的测试函数对未知的电流分布进行参数化，并根据测量数据确定各系数。对于稳态放电，需要进行连续平衡分析。Tore Supra CIEL项目的目标是研究持续时间长达1000秒的放电。我们报告了广泛使用的平衡代码EFIT的实时版本的开发进展。
