  • Inside height of vacuum chamber 3.39 m;
  • Wall width of vacuum chamber 5 … 8 mm;
  • Vacuum chamber volume 47m3;
  • Ultimate pressure 10-5Па;
  • Protective material on the wall – graphite FP479;
  • Material of vacuum chamber – stainless steel AISI 321.

Magnet system is designed for holding a hot plasma in divertor configuration. Magnetic coils produced from square-shape silverized copper tube. Cooling water circulate inside the coils. The copper wires are wrapped by isolation material and baked in vacuum furnace.

Pilot coils has the following dimensions:

  • inside diameter from 5050 mm to 6322 mm;
  • outside diameter from 5170 mm to 6640 mm;
  • height from 210 mm to 277 mm;
  • weight from 4050 kg to 6950 kg.

Toroidal-shaped coils (16 pcs) are mounted round about vacuum chamber of Tokamak. They generate radial magnet field. Coil height 4764 mm, width 285 mm, mass 7500 kg.

Plasma parameters:

  • big radius 1.48 m,
  • small radius 0.67 m,
  • current 2 MA,
  • , toroidal-shaped magnetic field 2 Tl.

Tokamak equipped by additional system for plasma heating with output power 15-20 MW. The reachable temperature about 5-9 keV for electron concentration ~1020 m-1. Discharge time is up to 30 s. Vacuum chamber of Tokamak is intended to generation of plasma with thermonuclear parameters. All measurement equipment are installed inside vacuum chamber.
