Cosmic neutrons radiation damage in carbon nanotubes for space applications
The main phenomenological aspects of the nuclear reactions induced by high-energy cosmic radiations in Carbon compounds are given. Results of measurements made with polycarbonate detectors at the International Space Station are shown and the main radiation damage mechanisms due to fast neutrons are discussed. Results of 0.02 DPA calculated value, indicate that carbon based matter start losing its intrinsic properties. Deterioration rate is further accentuated, when nuclear reactions are considered. Results evidence carbon nanometers structure radiation damage resistance of and show its suitability in space technology.
