The elements of the heavy ions accelerator DC-60 were manufactured at the G.N. Flerov Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research. The physical start-up of the accelerator took place at the end of 2006. The established accelerator complex is a large nuclear-physical facility intended for fundamental and applied physical research, as well as for technological works in the field of nuclear science and technologies, that meets the requirements of the world level.
Heavy ions accelerator DC-60 includes the following
- Ion source
- Cyclotron
- High-energy ions output channels
- High-energy ions irradiation chambers
- Chamber for polymer film irradiation
- Low-energy ions output channel
- Chamber for low-energy ions irradiation
The design of the heavy ions accelerator DC-60 was based on the highest possible versatility both in terms of the spectrum of accelerated ions and their energy and irradiation modes. Nevertheless, it was necessary to modify the standard modes for specific and technological works to suit the requirements of various tasks. Today, this accelerator is able to produce the beams of charged ions 12,13C, 14,15N, 16,17O, 32S, 20Ne, 40Ar, 84Kr, 132Xe and solids 6,7Li, 56Fe with energies of 0.5-1.75 MeV/nucleon.
The main applications of these ion beams are unique research in radiation materials science and ion implantation of materials, development of unique modification methods, including low temperature irradiation of materials, simulation of real conditions of reactor irradiation by fission fragments at temperatures of 300-1000 K, measurements of ionoluminescence during interaction of high-energy ions with materials, production of track membranes for membrane filters and membrane distillation.
Technical capabilities of the heavy ions accelerator DC-60 are suitable for the scientific-technological experiments on 4 channels using the ion beams from lithium to uranium with high currents in the following main areas: experiments in nuclear and radiation physics; testing of structural materials; modeling of cosmic rays; production of nuclear track membranes.
