The accelerating voltage is 0.4 to 1.7MV, and the maximum beam \ncurrent is 5microA at 3.4MeV. This system has three beam ports for \ndifferent types of PIXE analysis, conventional, micro-beam and in-air. \nNormal PIXE line has two types of X-ray detecting device, Si (Li) and \nCdZnTe detectors detectable for elements from Na (Z=11) to U (Z=92). \nFifteen samples can semi automatically be measured at one time with the \noptical beam size from 0.5 to 2.0 mm at 100 nA of the beam current. A \nquadruple triplet magnet (Model OM2000, Oxford Micro beams, Ltd.) attached \nto the other beam port produces a proton micro-beam of the square shape \nless than 1micron x 1micron. Micro-beam \nscanning PIXE analysis is carried out with this beam at 50pA current and \nscanning area up to 2.0mm square. The in-air PIXE analysis is performed \nusing the third beam port.\nIn this paper, we introduce micro-PIXE scanning system showing the ability \nto draw elemental maps in a spatial resolution of about 1 µm with \nanalyses of fish scale, fish otolith, crocus pollen and micro organisms. \nFine ring structure of a fish scale was observed using elemental mapping \nwith proton micro-beam scanning. Pollen was analyzed as one example of \nsingle cell to demonstrate the elemental distribution. Fish scale and \notolith seem to be a kind of time recorder like tree rings. And the \nelemental composition reflects the living condition. Therefore, fish scale \nand otolith are possible to be used as a biological indicator.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"3rd International Symposium on Nuclear Analytical Chemistry (NAC-III)","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yukawa, Masae"}],"nameIdentifiers":[{"nameIdentifier":"595948","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Imaseki, Hitoshi"}],"nameIdentifiers":[{"nameIdentifier":"595949","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"湯川 雅枝","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"595950","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今関 等","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"595951","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Introduction of PIXE anallysis system in National Institute of Radiological Sciences","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Introduction of PIXE anallysis system in National Institute of Radiological Sciences"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2003-08-26"},"publish_date":"2003-08-26","publish_status":"0","recid":"59906","relation_version_is_last":true,"title":["Introduction of PIXE anallysis system in National Institute of Radiological Sciences"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:59:42.749503+00:00"}
