Theoretical studies of MHD stability

Author:

Abstract

MHD instabilities limit the operating range of a tokamak both in current and pressure. The stability diagram of a low B ohmic plasma is discussed. Examples of instabilities driven by toricity and by pressure are given. Results of optimization lead to a scaling law for the maximum B that can be stably confined. It has not been overcome by experiments so far.
