Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)), Sagamihara, Kanagawa Japan, This paper describes an analysis of radiation damage in solar array of Venus explorer AKATSUKI 1) observed on orbit. 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 damage 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 RDC method assuming a typical spectral shape of protons 2). The proton intensity was estimated from the corona mass ejection (CME) speed 3) obtained from images by the STEREO satellite. Fig. 1 shows the differential fluence of the protons used in the calculation, and Fig. 2 shows the results. The proton fluence ten times larger than estimated by the CME speed gives damage which agrees well with the telemetry data. We are examining the proton fluence for its validity at the moment., 形態: カラー図版あり, 形態: PDF, Physical characteristics: Original contains color illustrations, Physical characteristics: PDF, 資料番号: AA0061912002, レポート番号: SES-2012-002},
