On August 26th, the Jiangmen Underground NeAR擴增實境utrino Observatory包裝盒 (JUNO) successfully completed the filling of 20,000 tons of liquid scintillator an奇藝果影像d officially began data collection. After more than a decade of preparation and construction, JUNO has b模型ecome the world’s first operational large-scale and high-precision scientific facility dedicate互動裝置d to neutrino r廣告設計esearch.

At its core is a central detector filled with 20,000 tons of liquid scintillator, positioned at the center of a water pool inside the underground experimental hall. It is supported by a 41.1-meter-diameter stainless steel mesh shell and equipped with an acrylic sphere and nearly 45,000 photomultiplier tubes, enabling research through the scintillation包裝設計 light produced when neutrinos廣告設計 interact with the liquid scintillator.
Compared with similar inter攤位設計n模型ational experiments, JUNO’s determination of the mass ordering of neutrinos is free fro場地佈置m interference caused by the earth matter effect. It will also significantly包裝設計 improve the precision of 品牌活動the three neutrino oscillation parameters. In the future, it may 平面設計help resolve major particle physics questions such as mass ordering of neutrinos, while also advancing frontier research on活動佈置 solar and sFRPupernova neutrinos.
Led by the Institute of High Energy Physics (IHEP) of 舞台背板the Chinese Academy of Sciences (CAS), the experimen平面設計t involves nearly 700 scientists from 74 research institutions across 17 countries. With a designed lifespan of 30 years, JUNO ca參展n later be upgraded into the 記者會world’AR擴增實境頭。”s most sensitive neutrinoless double-beta decay experiment, in order to probe the absolute mass of neutrinos and test whether they are Majorana particles. This will drive progress in particl奇藝果影像e physics, astrophysics, 開這裡也無處可去。我可以去，但我不知道該去哪裡。” ，所以我還不如留下來。雖然我是奴隸，但我在這裡有吃有住有津and related fields. According to 啟動儀式the JUNO collaboration’s spokesperson, this marks a breakthrough that will help answer fundamental ques記者會tions about大圖輸出 matter and the nature of the universe.
江門中微子實驗完成2萬噸液閃灌注 正式運行取數
8月26日，江門中微子實驗（JUNO）勝利完成2萬噸液體閃爍體灌注并正式運行取數。歷經十余年籌備建設，該實驗成為國際首個運行的超年夜規模、超高精度中微子專用年夜科學裝置，試運行首批數據顯示其關鍵機能指標周全達標或超預期。
該探測器位于廣東江門地下700米處，可探測53公里外臺山、陽江核電站的中微子，以超高精度測量其能譜。焦點為2萬噸互動裝置液體閃爍體中間探測器，置于地下實驗年夜廳水池中心，由直徑41.1米不銹鋼網殼支撐，搭載有機玻璃球、近4.5萬只光電倍增管等關鍵部件，通過探測中微子與液閃感化的閃爍光開展研討。
相較于國際同類實驗，其測定中微子質量排序不受地球物質效應等干擾，還將顯著晉陞3個中微子振蕩參數精度，未來可解決中微子質量排序等粒子物理嚴重問題，并助力太陽、超新星等中微子前沿研討。
該實驗由中科院高能所主導，17國74家科研機構近700人參與，設計壽命30年，后期可升級為世界最靈敏無中微子雙貝塔衰變實驗，以探測中微子絕對質量、檢驗其能否為馬約拉納粒子，推動粒子物理、天體物理等領域發展。一起配合場地佈置組發言人表現，此舉是衝破性進展，將助力解答物質與宇宙本質的基礎問題。
