Main physical and technological problems of construction of a tokamak with a strong magnetic field and plasma adiabatic compression

Technological problems of construction of a tokamak with a strong magnetic field and adiabatic plasma compression are considered. The results of sketch designing of the installation with the following parameters are presented: large filament radius after compression-0,415 m, small filament radius after compression-0,125 m, plasma current after two compressions up to 1,2 MA, mean plasma density upon two compressions up to 1015 cm -3, average plasma temperature upon compressions 7 keV, energy confinement time 30-100 ms. The toroidal field winding consist of 32 single-twin sections. Each section represents a massive twin of chromous bronze enclosed in a steel bandage. Maximum winding current is 830 kA, maximum magnetic field on the winding surface 21,2 T. A poloidal field is formed without using ferromagnetic core by means of inductor winding, compression winding, two equilibrium windings and two initial fiel, correction windings. The parameters of the power supply system of the toroidal field winding, inductor supply system and compression winding, equilibrium winding supply system, generak power supply system are given. Nowadays different versions of the metallic chamber design without cuts are studied
