摘要：

Energy approach to the problem of plasma stability against the resistive wall modes (RWMs) in tokamaks is proposed in a form allowing study of the fast and conventional slow modes on the same basis. A general dispersion relation for RWMs is derived and analyzed. It is shown that the standard thin-wall model may strongly underestimate their growth rate. Two opposite cases are compared, with a skin length much larger and much smaller than the wall thickness. (C) 2012 Elsevier B.V. All rights reserved.
