   Författare :Jenny-Ann Malmberg; KTH; []
   Nyckelord :Nuclear fusion; reversed field pinch; resistive wall instabilities; wall locked modes; tearing modes; resistive shell modes; field errors; Extrap T2; Extrap T2R; TPE-RX;

   Sammanfattning : It is relatively straightforward to establish equilibrium inmagnetically confined plasmas, but the plasma is frequentlysucceptible to a variety of instabilities that are driven bythe free energy in the magnetic field or in the pressuregradient. These unstable modes exhibit effects that affect theparticle, momentum and heat confinement properties of theconfiguration. LÄS MER

   Sammanfattning : Magnetically confined fusion (MCF) plasmas are typically subject to several unstable modes. The growth of one mode can limit the plasma energy confinement and might cause a termination of the plasma. Externally applied resonant magnetic perturbations (RMPs) are used to control and to mitigate some of the unstable modes. LÄS MER
