A complex imitator has been designed and built for a ground-based express imitation of six space factors. The device has no analogs in the Community of Independent States and in the ESA countries. The six factors are the radiation from an artificial Sun (/U, 200—2500 nm), vacuum UV radiation (/U, 5—200 nm), protons and electrons with energies of 50—200 keV in the Earth's radiation belts, vacuum (10~7 torr), thermocyclogenesis in the range 4.2—400 K. The space factors will be studied for their degrading effect on the physical and mechanical properties of various materials as well as on the normal operation of mechanisms and scale models of spacecraft. These experiments will make possible substantiated recommendations as to the use of the materials which are promising in the construction of space systems with lifetimes of 5—10 years.
