The output voltage of the solar array have shown sudden drops, which are most reasonably associated with radiation damage, three times since its launch. The analysis of these radiation damages is difficult, because no direct observation data of the spectra and the amount of the high-energy particles is available. We calculated the radiation damage using the relative damage coefficient (RDC) method assuming a typical spectral shape of protons., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0061889004, レポート番号: JAXA-SP-12-008E}, pages = {24--27}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {Analysis of Radiation Damage in On-orbit Solar Array of Venus Explorer Akatsuki}, volume = {JAXA-SP-12-008E}, year = {2013} }
