Effects of Thin Shell on the Resistive Wall Mode in Keda Torus eXperiment

POSTER

Abstract

Keda Torus eXperiment (KTX) is a new reversed field pinch (RFP) with a copper thin shell. The stability of resistive wall modes (RWMs) is crucial for the sustained operation of KTX. The standard formulation of dispersion relation for RWM based on the MHD energy principle has been evaluated for a cylindrical $\alpha-\Theta_{0}$ model of KTX plasma equilibrium, in an effort to investigate the effects of thin shell on the RWM in KTX. Full MHD calculations of the linear RWM in KTX using the NIMROD code are also being developed. The detailed comparisons between theoretical analyses and NIMROD calculation results, for KTX equilibria with and without rotation, are to be presented and discussed.
