Medical Center (LLUMC), California, USA. Investigators from 17 laboratories in 10 nations participated in these experiments. To date, five intercomparison experiments have performed at HIMAC using heavy ion beams, including He, C, Ne, Si, Ar and Fe, that are of importance in the galactic cosmic-ray spectrum. At LLUMC, an experiment was performed using a proton beam to simulate a solar particle event. Additional experiments, including an intercomparison using relativistic Fe, Si and proton beams at NSRL, are currently being planned. The objectives of the ICCHIBAN intercomparison experiments are to 1) determine the response of space radiation instruments to heavy ions and protons; 2) intercompare the response and sensitivity of these instruments; 3) establish and characterize an accelerator-based \"reference standard\" against which these instruments can be calibrated.\nThe participants of ICCHIBAN-1 and ICCHIBAN-2 experiments have analyzed their results and submitted reports to the ICCHIBAN working group (ICWG). ICWG has summarized the results and published as HIMAC Technical Report. For active instruments, the LET distributions from instruments using Si detectors and from TEPC were good agreement for 12C exposures, although the width of the main peak was broader for the TEPC exposures due to differences in the operating principles of the instruments. Several active instruments were found to lack sensitivity to high LET particles including the Fe beam used in the intercomparison. For passive dosimeters, ICWG exposed participants' dosimeters to both 'known' and 'blind' conditions. The participants analyzed their dosimeters from the 'known' exposures to measure dose linearity and obtain high-LET dose efficiency response. In the blind exposure simulating an actual exposure in space (97% low LET particles and 3% high LET particles) most of dosimeters showed good agreement with the reference ion chamber measurements. But, in other blind exposures where high LET radiation was dominant, there was larger disagreement. This was largely due to the lack of efficiency of TLD and OSL dosimeters in registering dose from high-LET particles. Some of participants applied correction methods to the TLD or OSL data that greatly improved their response to high-LET particles. Only those passive detector laboratories that used a combination of CR-39 PNTD and TLD were able to measure both dose and dose equivalent.","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 Workshop on Space Radiation Research","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":"Uchihori, Yukio"}],"nameIdentifiers":[{"nameIdentifier":"666031","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Benton, Eric"}],"nameIdentifiers":[{"nameIdentifier":"666032","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fujitaka, Kazunobu"}],"nameIdentifiers":[{"nameIdentifier":"666033","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasuda, Nakahiro"}],"nameIdentifiers":[{"nameIdentifier":"666034","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitamura, Hisashi"}],"nameIdentifiers":[{"nameIdentifier":"666035","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"666036","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内堀 幸夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"666037","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤高 和信","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"666038","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"安田 仲宏","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"666039","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北村 尚","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"666040","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":"ICCHIBAN Intercomparison Program for Space Radiation Instruments at HIMAC, LLUMC AND NSRL","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ICCHIBAN Intercomparison Program for Space Radiation Instruments at HIMAC, LLUMC AND NSRL"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-05-24"},"publish_date":"2004-05-24","publish_status":"0","recid":"67780","relation_version_is_last":true,"title":["ICCHIBAN Intercomparison Program for Space Radiation Instruments at HIMAC, LLUMC AND NSRL"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:33:48.079580+00:00"}
