论文摘要
一个新的平衡压力曲线扩展了具有简单统一表达式$ p = p = p = p(ψ;β_{s},α,σ)$的刚性旋转(RR)模型,并提出了分隔的内部和外部,其中提出了分离的内部和外部,其中radial radial raadiald归一化的现场反向构型(FRC)均衡的磁场可用于压力,磁场,并且现在可以确定磁性磁场,并且当前磁性磁场可以确定磁性,并且磁性磁场可以确定$β_S\ equiv p_s/2μ_0b_e^2 $和$δ_s\ equiv l_ {ps}/r_s $,其中$ p_s $是saparatrix的热压,$ b_e $是外部磁场强度,外部磁场强度,$ l_ {ps} $是分离的$ _________s $ rud yis rudiix,RATS $ rat rius rus rat rius。这种修改的刚性转子(MRR)模型具有足够的灵活性,可以容纳较窄的层(SOL)宽度和空心电流密度曲线,可用于满足实验测量值。分析和数值研究了新的MRR模型的详细一维(1D)特征,并且在二维(2D)数值平衡溶液中也证实了结果。
A new equilibrium pressure profile extending the Rigid-Rotor (RR) model with a simple unified expression $P=P(ψ;β_{s},α, σ)$ for both inside and outside the separatrix is proposed, in which the radial normalized field-reversed configuration (FRC) equilibrium profiles for pressure, magnetic field, and current can be determined by only two dimensionless parameters $β_s\equiv P_s/2μ_0B_e^2$ and $δ_s\equiv L_{ps}/R_s$, where $P_s$ is the thermal pressure at the separatrix, $B_e$ is the external magnetic field strength, $L_{ps}$ is the pressure profile scale length at the separatrix, and $R_s$ is the separatrix radius. This modified rigid rotor (MRR) model has sufficient flexibility to accommodate the narrow scrape of layer (SOL) width and hollow current density profiles, and can be used to fit experimental measurements satisfactorily. Detailed one-dimensional (1D) characteristics of the new MRR model are investigated analytically and numerically, and the results are also confirmed in two-dimensional (2D) numerical equilibrium solutions.
