摘要：
<正> The EFIT(Equilibrium Fitting)code is modified for the equilibrium configurationreconstruction in HL-2A.Signals from Langmuir probe(LP)at the divertor target platesare employed in the reconstruction of divertor configurations.The results show that discharge#2895 starts with a limiter configuration and develops gradually into a divertor configurationafter ￡=230 ms.This transition process is clearly demonstrated by the LP signals for the reconstruction.The profiles of plasma parameters such as safety factor q,pressure and current densityas well as the evolution of major shape parameters of plasma,such as the boundary magneticfluxes,the positions of both x-point and magnetic axis,are calculated from the reconstructedconfigurations.The possibility to apply the method to the swing of strike point on the targetplate is discussed.
