Description
A wide range collection of particle accelerators and neutron sources in Czech Republic provide well-defined particle beams and reference radiation sources of energies and intensities found in LEO orbit and outer space. They are suitably used for space radiation research, detector calibration and radiation shielding testing. Collectively, the facilities provide (i) protons in the range 100 keV to 238 MeV, (ii) 3He ions of energies 20 and 38 MeV, (iii) 4He and 12C ions of low energies in the range 1 MeV/u, (iv) electrons of energy 3-22 MeV, (v) mono-energetic fast neutrons of 2.5 MeV and 14.1 MeV from D-D and D-T generators, (vi) mono-energetic tunable fast neutrons in the ranges 400 keV – 1.8 MeV, 2.5-4.5 MeV and 15-17 MeV. A diagram list of the wide-range neutron sources in Czech Republic in terms of neutron energy and flux is given in the figure. Moreover, with customized materials nuclear setups provide extended quasi-mono-energetic and partly mixed-radiation fields of e.g. broad spectrum fast and slow neutrons and broad gamma fields. Additionally, high-power hard-spectrum RTG/X-ray units and radionuclide 60Co and 137Cs monoenergetic gamma-ray irradiators are also available. The overview and parameters of the radiation fields and particle beams for external users will be presented with focus on radiation shielding testing.
