Improvement of confinement in tokamaks by weakening of poloidal magnetic field near boundary

Theory of turbulent equipartition and experiment indicate that density, pressure, and temperature profiles follow to poloidal magnetic field profile. Therefore it is suggested to change magnetic geometry between core and boundary by toroidal conductors and/or plasma current. As a result density and temperature gradients will become steeper, and stored energy will be higher with low boundary plasma parameters. Suggested new mode of confinement may essentially simplify achieving of ignition.
