Such returned samples are handled by various techniques to prevent contamination from earth materials. So, we have adopted cleaning methods suitable for the material and application of tools, which will be introduced into the nitrogen-circulation-type clean chamber that handles the returned sample. The results of monitoring of cleanliness level of clean rooms and clean chamber after completions suggest that curation facility has been kept clean. Moreover, it was demonstrated that the atmosphere in the clean chamber was not affected by the clean room based on the metallic elements and organic materials., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA2030019000, レポート番号: JAXA-RR-20-004E}, title = {Cleanliness level of the Extraterrestrial Sample Curation Center of JAXA}, year = {2021} }
