“…In our opinion, the main cause of plasma instability (it is secondary) in a tokamak "donut" is the mutual generation of a toroidal two-component magnetic ield of 5 T strength and higher, created inside a tokamak, with a poloidal ield of conductors located on the outer side of the tokamak, exciting a poloidal ield with "Preload" of the heated plasma to the center of the toroidal cavity of the tokamak and "release" of the plasma from the walls of the tokamak. In this basic construction, as it seems, one important circumstance, described in detail in [9,12], is not taken into account. This circumstance is due, as is mentioned above, to a possible self-generation of the main toroidal magnetic ield H T inside the tokamak "donut" with a poloidal ield H P .…”
