The potential of the radiation effects investigations on the accelerator facilities at Gatchina

The accelerator facilities at Gatchina which are used both for basic physics purposes and for investigation of the radiation effects are described. The 1 GeV synchrocyclotron is a basic accelerator facility at Gatchina. The proton energy is fixed and equals 1 GeV, the extracted beam intensity can be varied from 106 up to 6.1012 l/s. The long burst operation system provides variation of the beam macro pulse duration from 300 μs up to 10 ms. A meson-production target installed in the accelerator hall is used through 3 meson channels that can operate simultaneously. The neutron generator (NG) is another facility at Gatchina. The yield of 14 MeV neutrons if up to 2.1012 /s and the irradiation facility allows a neutron flux up to 1011 n.cm-2.s-1 on the irradiated sample. The electrostatic accelerator (ESA) accelerates protons, deuterons and electrons in the range of 0,3 - 1,8 MeV. The intensity of the ion beam is from 1 nA up to 30 μA. (A.C.)
