Effect of Locked MHD Modes on the Efficiency of Plasma Heating by the Neutral Beam Injection Method at the Globus-M2 Spherical Tokamak

Effect of Locked MHD Modes on the Efficiency of Plasma Heating by the Neutral Beam Injection Method at the Globus-M2 Spherical Tokamak

A set of magnetic coils used to correct the error fields at the Globus-M2 spherical tokamak, which appear due to the imperfections of the production and assembly of the tokamak magnetic system, is described. The magnetic sensors that are used to monitor the locked helical MHD modes are also describe...

Description
Summary:A set of magnetic coils used to correct the error fields at the Globus-M2 spherical tokamak, which appear due to the imperfections of the production and assembly of the tokamak magnetic system, is described. The magnetic sensors that are used to monitor the locked helical MHD modes are also described. The results of experiments on detecting the locked modes in the discharges with plasma heating by neutral beam injection are presented. A correlation is found between the appearance of the locked modes accompanied by the loss of fast ions and the confinement of the main plasma.
