Metal ion accelerator for simulation studies of reactor materials

Purpose. The development is intended for work on extending the life of nuclear power plants.

Specifications.

  • Beam ion type Be, Fe, Cr, Ni, Zr, Mo, W
  • Ion current in the receiving chamber, µA 10-200
  • Ion energy, keV 20-300
  • Ion charge +1, +2
  • Power consumption, 3000 W.

Area of use. Energy (thermal and nuclear power plants).

Advantages. The accelerator allows you to perform simulation studies of radiation damage to materials of reactor technology on beams of accelerated metal ions with a wide mass spectrum (Fe, Zr, Mo and others) in the range of irradiation doses (0.1–300 displacements per atom) and temperature range 80–1000 ° C The vacuum in the receiving chamber in the irradiation mode is 1.2·10–4 Pa. The irradiation period is 3-4 orders of magnitude less than the irradiation with reactor neutrons. The low level of partial pressure of water vapor significantly reduces the degree of oxidation of the irradiated samples. The facility is equipped with a source of single- and double-charged metal ions based on ion-plasma sawing.

Description. Simulation studies of the effect of ion irradiation on structural materials of nuclear/thermonuclear technology using heavy metal ions (Be, Fe, Cr, Ni, Zr, Mo, W, etc.) and ion implantation of materials with singly or doubly charged metal ions.
