Photons produced by a particle in a detector possess essential information on the particle's properties.  They are utilized for particle identification in Cherenkov counters and TOF counters, for particle tracking in scintillating fiber detectors and for energy measurement in calorimeters.  An interesting and attractive photon sensor is a hybrid photo-detector (HPD) equipped with a multi-pixel avalanche diode.  An HPD can be realized based on vacuum-tube technology and the rapidly evolving semiconductor technology.  The latter is the key<br />element for multi-pixel readout with single-p oton sensitivity.<br />  We have investigated various types of avalanche diodes (AD) appropriate for electron multiplication, and have successfully developed an HPD equipped with the most practical AD.  The developed HPD has an effective area of 16x16 mm2 with 8x8 pixels of 2x2 mm2 each.  The gain is 5x10 4, sufficiently high to detect single photons with a timing resolution better than 100 ps.  Photoelectrons from 1 to 5 can be clearly identified in a pulse-height spectrum as distinct peaks, thanks to the low noise characteristics of the HPD.  In addition, it has been proved that the HPD can be operated with good performance in a magnetic field of up to 1.5T.  A superb feature of this HPD as a particle tracker has been demonstrated by a measurement of muon tracks in cosmic-rays with a detector system consisting of a bundle of scintillating fibers and an HPD.<br />  In this way, the developed HPD has successfully functioned as a multi-pixel photon sensor. This is the first HPD having all desirable features, such as high granularity, single-photon sensitivity, fast timing capability and operability under high magnetic fields, which are essential requirements in applications for high-energy physics experiments.","subitem_description_type":"Other"}]},"item_1_description_18":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_description_7":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"総研大甲第652号","subitem_description_type":"Other"}]},"item_1_select_14":{"attribute_name":"所蔵","attribute_value_mlt":[{"subitem_select_item":"有"}]},"item_1_select_8":{"attribute_name":"研究科","attribute_value_mlt":[{"subitem_select_item":"数物科学研究科"}]},"item_1_select_9":{"attribute_name":"専攻","attribute_value_mlt":[{"subitem_select_item":"14 素粒子原子核専攻"}]},"item_1_text_10":{"attribute_name":"学位授与年度","attribute_value_mlt":[{"subitem_text_value":"2002"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"SUYAMA, Motohiro","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":"2016-02-17"}],"displaytype":"simple","filename":"甲652_要旨.pdf","filesize":[{"value":"206.6 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"要旨・審査要旨 / Abstract, Screening Result","url":"https://ir.soken.ac.jp/record/689/files/甲652_要旨.pdf"},"version_id":"9a6681c4-7ff2-4320-80bf-0625ba979ea7"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"simple","filename":"甲652_本文.pdf","filesize":[{"value":"2.6 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"本文","url":"https://ir.soken.ac.jp/record/689/files/甲652_本文.pdf"},"version_id":"c7607b8a-9711-4718-9ae3-3307f14ed041"}]},"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":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"Development of a multi-pixel photon sensor with single-photon sensitivity","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of a multi-pixel photon sensor with single-photon sensitivity"},{"subitem_title":"Development of a multi-pixel photon sensor with single-photon sensitivity","subitem_title_language":"en"}]},"item_type_id":"1","owner":"1","path":["16"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-22"},"publish_date":"2010-02-22","publish_status":"0","recid":"689","relation_version_is_last":true,"title":["Development of a multi-pixel photon sensor with single-photon sensitivity"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T14:51:04.737903+00:00"}
