[en] The results of preliminary consideration of a compact tokamak with a strong magnetic field designed for achievement and investigation of thermonuclear burning are presented. A model of the compact tokamak with ignition with the following parameters: aspect ratio of plasma filament A-5; the large radius of plasma filament 2.2 m; the small radius- 0.44 m; the diverter-poloidal, two-zero; stretch by the vertical 1.7; current in the plasma filament 3.8 MA; plasma density in the burning regime, average 6-8x10¹⁴ cm^-3, on the axis 1-5x10¹⁵ cm^-3; temperature on the axis 10 keV; ignition margin 1-2; heating before ignition by means of ion cyclotron resonance at negligible He³ addition addition, f=104 mHz, P_HF=12 MW; heating duration 3-5 s, is considered. Systems of a poloidal field and HF-heating, a discharge chamber and a power supply system are described. Stress-deformed state as well as strength of the electromagnetic system and discharge chamber are considered
