At first, the relationship between resonance peak characteristics and the plasma parameter were studied. Actually electron density determination using the resonance probe is very difficult because sensitivity of anti-resonance dip which gives electron density, is very low, and usually it is masked by plasma noise and potential drift. The differential resonance probe which was developed in order to avoid these impediments, has two symmetrical floating probes. One acts as a single resonance probe, while the other one gives the reference floating potential of plasma. Using a differential amplifier, common mode noise is removed. In this paper, the properties of the differential resonance probe which show anti-resonance clearly are considered, together with the accuracy of the probe. At first, the theoretical approach of the resonance probe in magneto plasma is performed using plasma impedance theory at radio frequency. It is shown that anti-resonance frequency of the resonance probe is upper hybrid frequency, the same as in the impedance probe. Second, the experimental results are compered with theoretical caliculations. Comparision of properties of the differential resonance probe are performed using low temperature (about 0.1eV) and low density (10^4 -10^6el/cc) in space simulation chamber (diameter 2m, length 3m) using back diffusion type plasma source, and ionosheric plasma using sounding rocket. Experimental results show that electron density computed by the above two methodes agree with an error range of ± serveral percent in uniform plasma. Deviation of the results of electron density by impedance probe from the results of the resonance probe occue when the potential difference between plasma potential and potential of rocket body or probe supporter is large. The resonance probe has an insulated probe bottom to escape the sheath of the capacitance. This effect of apparent low density measured by the impedance probe is verified by laboratory experiments.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0124802000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8100","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00161914","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"大阪市大工学部"},{"subitem_text_value":"大阪市大工学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"南, 繁行"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"竹屋, 芳夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MINAMI, Shigeyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKEYA, Yoshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-23"}],"displaytype":"detail","filename":"SA0124802.pdf","filesize":[{"value":"618.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0124802.pdf","url":"https://jaxa.repo.nii.ac.jp/record/31761/files/SA0124802.pdf"},"version_id":"d0dd61d5-534c-4e86-915c-50e86b6f18c2"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"電離層プラズマを用いた2つのRFプローブの比較実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"電離層プラズマを用いた2つのRFプローブの比較実験"}]},"item_type_id":"9","owner":"1","path":["1890","1910"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"31761","relation_version_is_last":true,"title":["電離層プラズマを用いた2つのRFプローブの比較実験"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:51:25.621225+00:00"}
