Quick identification of EAST plasma discharge shape

Abstract

To meet the requirement of plasma shape control running mode on experimental advanced superconducting tokamak(EAST), this paper studies the quick identification algorithm of plasma discharge shape and gives the results of reconstruction simulation. Moreover, the code is checked by the equilibrium reconstruction code EFIT provided by GA in U.S.A. Results show that we can identify the shape quickly by using external magnetic measurements and appropriate current profile in conjunction with real time equilibrium reconstruction algorithm.
