(2) | 西元年:2014 研究人員(中):王子敬、『中國暗物質實驗』合作團隊,共74作者,其中包括中研院主導『台灣微中子實驗』參與之隊伍,來自台灣與印度的12作者。 研究人員(英):WONG, HENRY TSZ-KING, CDEX Collaboration consists of 74 authors, in which the Academia Sinica-led TEXONO Program participates with 12 members from Taiwan and India. 研究成果名稱(中):於中國錦屏山地下實驗以超低能量高純鍺探測器找尋暗物質 研究成果名稱(英):Limits on WIMP Dark Matter Searches with a Germanium Detector with sub-keV Sensitivitiy at the China Jinping Underground Laboratory 簡要記述(中):本院物理研究所主導之『台灣微中子實驗』(TEXONO)國際團隊,參與『中國暗物質實驗』(CDEX),找尋暗物質。團隊在2014年11月發表新數據,成果刊登於《物理評論D》(Physical Review D)。 TEXONO團隊的前期工作,成功的開啟了"sub-keV"探測器能區與找尋低質量暗物質的視窗,該質量範圍輾轉發展為國際暗物質研究的焦點。站在技術基礎上,團隊中以北京清華大學為首的隊伍,在中國四川蓋建了世界最深的『中國錦屏山地下實驗室』(CJPL),組織CDEX團隊,全力開展暗物質的研究。 國外的數個暗物質實驗(DAMA,CRESST,CoGeNT)提出的數據,可解讀成支持低質量暗物質存在的證據,但這與別的實驗卻有矛盾,因此引起爭議。TEXONO與CDEX團隊,發展嶄新的PCGe探測器刻度技術與數據分析方法,提高實驗靈敏度,解诀了處理「內裏事例」與「表面事例」效率修訂的癥結問題 ,否定以上實驗對暗物質證據的詮釋,並啟示其對數據處理之不足。 簡要記述(英):The Academia Sinica-based Taiwan Experiment On Neutrino (TEXONO) Program is a founding partner of the China Dark matter EXperiment (CDEX) . The Collaboration reported new results as a Rapid Communication in Physical Review D in November 2014. Earlier work by the TEXONO group has successfully opened the "sub-keV" window of investigation with novel germanium detectors for light dark matter searches. These advances inspire collaborators from Beijing Tsinghua University to lead construction of the China Jinping Underground Laboratory (CJPL) in Sichuan, and conducting the CDEX dark matter search program . Several experiments elsewhere (DAMA,CRESST,CoGeNT) reported data that could be interpreted as evidence for the detection of light dark matter, contradicted by results of others. The issue remains controversial. The Collaboration makes advances in low-energy germanium detectors and devises novel calibration schemes and data analysis techniques to differentiate between "Bulk" and "Surface" events. New results from the CDEX experiment at CJPL refute the evidence of dark matter in the region implied by these experiments, and indicate deficiencies in the original data analysis procedures.

(3) | 西元年:2013 研究人員(中):王子敬、[台灣微中子實驗] 國際合作團隊 (中研院主導,共38作者、9研究單位,來自台灣、中國、印度、土耳其) 研究人員(英):WONG, HENRY TSZ-KING, TEXONO Collaboration (led by Academia Sinica, including 38 authors from 9 institutes from Taiwan, China, India and Turkey) 研究成果名稱(中):於國聖核電廠微中子實驗室以超低能量高純鍺探測器測量暗物質之上限值 研究成果名稱(英):Limits on Spin-Independent Couplings of WIMP Dark Matter with a p-Type Point-Contact Germanium Detector at Kuo-Sheng Reactor Neutrino Laboratory 簡要記述(中):本院物理研究所主導之『台灣微中子實驗』(TEXONO)國際合作團隊於今(2013)年3月發表新數據,否定美國CoGeNT實驗於2011年發表有關暗物質的證據及詮釋,並引證其數據處理不足之處。此項研究成果將於2013年6月25日刊登於《物理評論通訊》(Physical Review Letters)。 宇宙的主要成分──暗能量和暗物質,為本世紀基礎科學之重要問題,亦為前端科技致力探索的研究方向。美國的CoGeNT實驗於2011年發表的數據,可解讀為支持低質量暗物質存在的證據。這論點若成立,將是革命性的發現,因此必須接受嚴格的驗證。「台灣微中子實驗」(TEXONO)國際合作團隊,累積多年開展極低能高純鍺探測器的技術,利用「國聖微中子實驗室」低背境屏蔽裝置,再發展嶄新的探測器刻度技術與數據分析方法,提高實驗靈敏度。TEXONO團隊發表的實驗數據,結論是在CoGeNT提出的範圍內,並沒有找到暗物質,駁斥該實驗詮釋。實驗的關鍵技術,是在排除背境事例中,必須作篩選效率的測量。TEXONO的數據,說明CoGeNT實驗在此環節上之不足。 TEXONO團隊持續提升探測器靈敏度,減低背境訊號,同時與中國大陸清華大學為首的研究團隊合作,在位於中國四川,為目前世界最深的「中國錦屏山地下實驗室」進行研究,以其極底宇宙線輻射背境的優勢,運用團隊已掌握的技術經驗,開展找尋暗物質的研究計畫。預期可更上層樓,站在國際舞台前端,進一步拓展偵測暗物質的實驗視窗。 「台灣微中子實驗」(TEXONO),為本院物理所主導之國際研究計畫,有來自台灣、中國大陸、印度與土耳其的研究單位參與,並得本院深耕計畫與國科會經費支持。團隊於2000年在台電核二廠建置『國聖微中子實驗室』,在微中子磁矩、微中子電弱作用等課題上,取得世界水準的成績,為國際同儕肯定。團隊自2004年兼納暗物質的偵測為主軸研究項目,成功開啟了偵測低質量暗物質的視窗,該質量範圍輾轉發展為國際暗物質研究的焦點。本研究成果,進一步確立團隊在找尋暗物質研究中的貢獻。 簡要記述(英):The Academia Sinica-based Taiwan Experiment On Neutrino (TEXONO) Collaboration led by the Institute of Physics recently reported research results that refute evidence presented by the Coherent Germanium Neutrino Telescope (CoGeNT) Collaboration on the detection of dark matter. The related article was published in the prestigious journal Physical Review Letters on 25 June, 2013. There is compelling evidence that about 95% of the energy density of the Universe is made up of dark matter and dark energy. However, the experimental search for dark matter and dark energy has proved challenging, and has become an important frontier in contemporary physics and cosmology. In 2011, the US-based CoGeNT Collaboration reported data that could be interpreted as evidence for the detection of dark matter. If confirmed, this evidence would constitute a revolutionary discovery and therefore requires rigorous verification. The TEXONO Collaboration successfully took up this challenge. Using advanced low-energy germanium detectors at the low-background facilities at the “Kuo-Sheng Reactor Neutrino Laboratory” in northern Taiwan, the research team devised novel calibration schemes and data analysis techniques to enhance experimental sensitivity. New results from the TEXONO investigation refute the evidence of dark matter in the region implied by the CoGeNT data, and indicate deficiencies in the original data analysis procedures. The principal technical advance of this work is on the measurement of efficiency in the rejection of background events. Founded in 1997, the TEXONO Collaboration consists of research institutes from Taiwan, China, India and Turkey, and is led by the Institute of Physics, Academia Sinica. The group pioneered techniques on the study of dark matter and strives to advance detector performance and physics sensitivities via hardware upgrades and background reduction. It built and commissioned the “Kuo-Sheng Reactor Neutrino Laboratory” at Nuclear Power Station II on the northern coast of Taiwan in 2000. TEXONO has achieved world-class results in studies of neutrino magnetic moments and neutrino electroweak physics, and launched an additional dark matter research program in 2004. The Collaboration has been working with Tsinghua University in China since 2009 to conduct the first dark matter experiment at the “China Jinping Underground Laboratory” in Sichuan, which is the deepest operating underground laboratory in the world and provides excellent shielding against the radiation background from cosmic rays. The newly reported results further establish TEXONO as a frontline contender in the quest for dark matter. Funding for the current research was provided by the Academia Sinica Principal Investigator Award, the National Science Council of Taiwan, and the Scientific and Technological Research Council of Turkey.

We achieved measurements on the electroweak interaction parameters and placed constraints on physics beyond the standard model. The results were published in two articles in Physical Review D. |

This provides a unique probe to WIMP dark matter with mass below 10 GeV. With a data acquisition live time of 0.338 kg-day at the Kuo-Sheng Laboratory, constraints on WIMPs in the galactic halo were derived. The limits improve over previous results on both the spin-independent WIMP-nucleon and the spin-dependent WIMP-neutron cross-sections for WIMP mass between 3-6 GeV. Sensitivities for full-scale experiments are projected. This detector technique makes the unexplored sub-keV energy window accessible for new neutrino and dark matter experiments. Two appendices are included after Version-3 to address questions raised on trigger and selection efficiencies as well as other issues.

Rev. D 75, 012001 (2007). 簡要記述(英):A search of neutrino magnetic moments was carried out at the Kuo-Sheng Nuclear Power Station at a distance of 28 m from the 2.9 GW reactor core. With a high purity germanium detector of mass 1.06 kg surrounded by scintillating NaI(Tl) and CsI(Tl) crystals as anti-Compton detectors, a detection threshold of 5 keV and a background level of 1 counts/(kg-keV-day) near threshold were achieved. Details of the reactor neutrino source, experimental hardware, background understanding and analysis methods are presented. Based on 570.7 and 127.8 days of Reactor ON and OFF data, respectively, at an average Reactor ON electron anti-neutrino flux of 6.4 X 10^{12 cm^{-2} s^{-1}, the limit on the neutrino magnetic moments of < 7.4 X 10^{-11} Bohr magneton at 90% confidence level was derived. Indirect bounds on radiative decay lifetimes were inferred. This final results of this work were published in Phys. Rev. D 75, 012001 (2007).
