Sadece 59 g\u00fcnl\u00fck veri toplama<\/strong> s\u00fcresi sonras\u0131 elde edilen erken sonu\u00e7lar, JUNO\u2019nun n\u00f6trino fizi\u011finde \u00f6nc\u00fc \u00f6l\u00e7\u00fcmler yapmaya haz\u0131r oldu\u011funu ortaya koydu. Dedekt\u00f6r, \u00f6zellikle G\u00fcne\u015f n\u00f6trinolar\u0131n\u0131n sal\u0131n\u0131m parametrelerini \u00f6nceki t\u00fcm deneylerin toplam\u0131ndan 1,6 kat daha hassas<\/strong> bir \u015fekilde \u00f6l\u00e7meyi ba\u015fard\u0131.<\/p>\n

Bu parametreler hem G\u00fcne\u015f hem de reakt\u00f6r antin\u00f6trinolar\u0131 kullan\u0131larak hassas \u015fekilde belirlenebiliyor. \u00d6nceki \u00e7al\u0131\u015fmalar, bu iki y\u00f6ntem aras\u0131nda 1,5 sigma\u2019l\u0131k hafif bir farkl\u0131l\u0131k g\u00f6stermi\u015fti. Bilim d\u00fcnyas\u0131nda \u201cG\u00fcne\u015f n\u00f6trino gerilimi\u201d olarak adland\u0131r\u0131lan bu durum, olas\u0131 yeni fizik senaryolar\u0131na i\u015faret ediyordu. JUNO\u2019nun yeni \u00f6l\u00e7\u00fcm\u00fc, bu fark\u0131 do\u011frulayarak yaln\u0131zca hem G\u00fcne\u015f hem de reakt\u00f6r n\u00f6trinolar\u0131n\u0131 kullanarak test edilebilecek bir platform sundu.<\/p>\n

Dedekt\u00f6r\u00fcn teknik detaylar\u0131<\/b><\/p>\n

<\/span> JUNO, 700 metre derinlikte bir granit da\u011f\u0131n alt\u0131na in\u015fa edilmi\u015f, k\u00fcre \u015feklinde dev bir dedekt\u00f6rden olu\u015fuyor. Dedekt\u00f6r\u00fcn merkezi 20.000 ton s\u0131v\u0131 sintilat\u00f6r i\u00e7eriyor ve bu k\u00fcre, 44 metre derinli\u011finde bir su havuzunun ortas\u0131nda yer al\u0131yor. 41,1 metre \u00e7ap\u0131nda paslanmaz \u00e7elik kafes ile desteklenen 35,4 metre \u00e7ap\u0131ndaki akrilik k\u00fcre, s\u0131v\u0131 sintilat\u00f6r\u00fcn yan\u0131 s\u0131ra 45.000\u2019den fazla fotomultiplier t\u00fcp (PMT), kablolar, manyetik koruma bobinleri ve \u0131\u015f\u0131k engelleyicilerle donat\u0131ld\u0131. <\/figure>\n

JUNO\u2019nun konsepti 2008\u2019de ortaya at\u0131ld\u0131 ve 2013\u2019te onaylan\u0131p fonland\u0131. 2014\u2019te uluslararas\u0131 katk\u0131lar da sa\u011fland\u0131. Yeralt\u0131 laboratuvar\u0131n\u0131n in\u015faat\u0131 2015\u2019te ba\u015flad\u0131. Dedekt\u00f6r kurulumu ise 2021\u2019de ba\u015flay\u0131p 2024 sonundan tamamland\u0131. Dedekt\u00f6r, ultra saf su ve 20 kiloton s\u0131v\u0131 sintilat\u00f6r ile doldurulduktan sonra 26 A\u011fustos 2025\u2019te fizik veri toplamaya ba\u015flad\u0131.<\/p>\n

N\u00f6trinolar, B\u00fcy\u00fck Patlama\u2019dan sonra var olan en eski par\u00e7ac\u0131klardan biri olarak biliniyor. Ancak neredeyse \u0131\u015f\u0131k h\u0131z\u0131nda ilerleyen bu par\u00e7ac\u0131klar son derece d\u00fc\u015f\u00fck k\u00fctleleri ve elektriksel y\u00fck ta\u015f\u0131mamalar\u0131 nedeniyle di\u011fer maddeyle neredeyse hi\u00e7 etkile\u015fime girmiyor. Bu nedenle \u201chayalet par\u00e7ac\u0131klar\u201d olarak an\u0131l\u0131yor.<\/p>\n

JUNO\u2019nun temel odak noktas\u0131 ise antin\u00f6trino ad\u0131 verilen n\u00f6trino antipartik\u00fcllerini incelemek. Tesisin yak\u0131n\u0131ndaki iki n\u00fckleer santralden gelen antin\u00f6trinolar, dedekt\u00f6r\u00fcn s\u0131v\u0131s\u0131yla temas etti\u011finde ani bir \u0131\u015f\u0131k patlamas\u0131 olu\u015fturacak. Ara\u015ft\u0131rmac\u0131lar, bu \u0131\u015f\u0131k patlamalar\u0131n\u0131 kaydederek antin\u00f6trino etkile\u015fimlerini analiz edecek.<\/p>\n

N\u00f6trinolar\u0131n \u00fc\u00e7 farkl\u0131 t\u00fcrde oldu\u011fu biliniyor; elektron n\u00f6trinosu, m\u00fcon n\u00f6trinosu ve tau n\u00f6trinosu. JUNO ara\u015ft\u0131rmac\u0131lar\u0131 bu \u00fc\u00e7 farkl\u0131 par\u00e7ac\u0131\u011f\u0131 k\u00fctlelerine g\u00f6re s\u0131ralayarak n\u00f6trinolar\u0131n deneysel olarak ilk kez 1942 y\u0131l\u0131nda tespit edilmesinden bu yana n\u00fckleer fizik\u00e7ilerin \u00fczerinde spek\u00fclasyon yapt\u0131\u011f\u0131 pek \u00e7ok sorudan birini \u00e7\u00f6zmeyi ama\u00e7l\u0131yor.<\/p>\n\n
