The spurious signal which appears on a pyroelectric detector is efficiently eliminated by setting a mask close to the detector, which has a function of avoiding the direct incidence of photons on its electrode. This is verified with the consistency of integrated value of the signal. The detector is calibrated with a HeNe laser taking the reflection on the detector surface into account. No temporal change has been seen on the sensitivity or the detector calibrated by this method. We also developed a thin metal-film bolometer with high sensitivity (12.9Ω/mJ) , high time response (3 μs) and well defined thermal characteristics. The calibration of this detector was performed by supplying a bias  current through its resistor. We constructed a bolometric system which consisted of twelve pyroelectric detectors and a metal-film bolometer with high time response and high spatial  resolution. The radiation power measured with the pyroelectric detector agrees with that measured with the calibrated metal-film bolometer within 10 %. Spectroscopic and bolometric measurements with spatial and temporal resolution show that large radiation loss brings about the decrease in electron and ion temperature and plasma energy. Carbon limiters have an effect to suppress the radiation power for ohmic plasma, but are insufficient for ICRF heated plasma. The main contribution to radiation power may be attributed to Fe impurity released from the ICRF antennae, the Faraday shield and vacuum vessel. By making carbonization or the wall and in-vessel components, the Fe impurity is suppressed to a low level (nFe /ne　～ 0.04 %) and the radiation power is reduced to Prad /(PoH +P_rf )　~ 20 % and emissivity throughout the plasma region is reduced. This is clearly supported by the observation of Z_eff reduction (3.9→1.2).", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_12_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "名古屋大学博士学位論文 学位の種類 : 理学博士(課程) 学位授与年月日 : 昭和62年3月25日", "subitem_description_language": "ja", "subitem_description_type": "Other"}]}, "item_12_dissertation_number_65": {"attribute_name": "学位授与番号", "attribute_value_mlt": [{"subitem_dissertationnumber": "乙第1923号"}]}, "item_12_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/12553"}]}, "item_12_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_12_text_14": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}, {"subitem_text_value": "application/pdf"}]}, "item_12_text_63": {"attribute_name": "学位授与年度", "attribute_value_mlt": [{"subitem_text_value": "1986"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "小川, 勇", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "32243", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ogawa, Isamu", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "32244", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "ko1923_abstr.pdf", "filesize": [{"value": "135.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 135300.0, "url": {"label": "ko1923_abstr.pdf ", "objectType": "abstract", "url": "https://nagoya.repo.nii.ac.jp/record/10711/files/ko1923_abstr.pdf"}, "version_id": "dbff7d43-f824-4c06-8b8c-f6f290cba027"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 1, "filename": "ko1923.pdf", "filesize": [{"value": "10.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 10500000.0, "url": {"label": "ko1923.pdf ", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/10711/files/ko1923.pdf"}, "version_id": "ecfce1d4-cb0e-4483-aaf8-8f27357eaf36"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "doctoral thesis", "resourceuri": "http://purl.org/coar/resource_type/c_db06"}]}, "item_title": "Measurement of Radiation Power from the JIPP T-IIU Tokamak Plasma : JIPP T-IIUトカマクプラズマからの放射強度測定", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Measurement of Radiation Power from the JIPP T-IIU Tokamak Plasma : JIPP T-IIUトカマクプラズマからの放射強度測定", "subitem_title_language": "en"}]}, "item_type_id": "12", "owner": "1", "path": ["636"], "permalink_uri": "http://hdl.handle.net/2237/12553", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2009-12-24"}, "publish_date": "2009-12-24", "publish_status": "0", "recid": "10711", "relation": {}, "relation_version_is_last": true, "title": ["Measurement of Radiation Power from the JIPP T-IIU Tokamak Plasma : JIPP T-IIUトカマクプラズマからの放射強度測定"], "weko_shared_id": -1}
