We determine the parameters of a tokamak reactor plasma that attains ignition in the same regime of collisionality, v^A/u^, as present-day Ohmic-heated tokamak plasmas. The 'collisional' regime is attractive because the presently observed confinement scaling, m-oc n 2 , can be employed, and fusion power densities can be very large (~10 W/cm 3 ). The use of Nb 3 Sn toroidal field coils and a plasma elongation % 1. 5 are necessary to attain the high plasma density ( n » 5 x 10 14 to 10 15 cm" 3 ) required for ignition in this low-temperature collisional regime.

The purpose of this theoretical investigation is the modeling of finish-strengthening under conditions of a rotating field for the definition of ferromagnetic indenter kinematic properties. This method is based on functioning devices offered by D.D. Logvinenko. The basis of these devices is an inductor located into the case. This inductor represents a modified stator of an induction motor. In the stator bore there is installed a cylindrical pipe made of nonmagnetic material the inner surface of which limits a working area of the device. From the obtained results of theoretical researches it follows that the kinematic properties of ferromagnetic indenters are defined by field parameters – induction of a direct and an alternating fields, frequency and gradient of induction of an alternating field, and also magnetic and inertial properties of indenters.
