Abstract We present the results of a search for core-collapse supernova neutrinos, using long-term KamLAND data from 2002 March 9 to 2020 April 25. We focus on the electron antineutrinos emitted from supernovae in the energy range of 1.8–111 MeV. Supernovae will make a neutrino event cluster with the duration of ∼10 s in the KamLAND data. We find no neutrino clusters and give the upper limit on the supernova rate to be 0.15 yr⁻¹ with a 90% confidence level. The detectable range, which corresponds to a >95% detection probability, is 40–59 kpc and 65–81 kpc for core-collapse supernovae and failed core-collapse supernovae, respectively. This paper proposes to convert the supernova rate obtained by the neutrino observation to the Galactic star formation rate. Assuming a modified Salpeter-type initial mass function, the upper limit on the Galactic star formation rate is <(17.5–22.7) M_⊙ yr⁻¹ with a 90% confidence level.

<title>Abstract</title> We report a search for electron antineutrinos at KamLAND with an 8.3−30.8 MeV energy range via the inverse beta decay. In 6.72 kton-yr of KamLAND data, we found 18 neutrino candidates and no significant excess over estimated backgrounds. From data interpretation, with the assumption of some supernova relic neutrino spectrum predictions, we give upper flux limits of 60−110 cm⁻² s⁻¹ (90% CL) in the analysis range and present a model-independent flux. These upper limits are the most stringent for 8−13 MeV region. We also improve on the upper probability limit of ⁸B solar neutrinos converting into antineutrinos via the Resonant Spin Flavor Precession with the neutrino magnetic moment. Besides, we could set limits on the annihilation cross-section for light dark matter pairs to neutrino pairs.

The reactor neutrino and gallium anomalies can be tested with a 3-4 PBq (75-100 kCi scale) 144Ce-144Pr antineutrino beta-source deployed at the center or next to a large low-background liquid scintillator detector. The antineutrino generator will be produced by the Russian reprocessing plant PA Mayak as early as 2014, transported to Japan, and deployed in the Kamioka Liquid Scintillator Anti-Neutrino Detector (KamLAND) as early as 2015. KamLAND's 13 m diameter target volume provides a suitable environment to measure the energy and position dependence of the detected neutrino flux. A characteristic oscillation pattern would be visible for a baseline of about 10 m or less, providing a very clean signal of neutrino disappearance into a yet-unknown, sterile neutrino state. This will provide a comprehensive test of the electron dissaperance neutrino anomalies and could lead to the discovery of a 4th neutrino state for Delta_m^2 > 0.1 eV^2 and sin^2(2theta) > 0.05.

More details Close

We propose to test for short baseline neutrino oscillations, implied by the recent reevaluation of the reactor antineutrino flux and by anomalous results from the gallium solar neutrino detectors. The test will consist of producing a 75 kCi 144Ce - 144Pr antineutrino source to be deployed in the Kamioka Liquid Scintillator Anti-Neutrino Detector (KamLAND). KamLAND's 13m diameter target volume provides a suitable environment to measure energy and position dependence of the detected neutrino flux. A characteristic oscillation pattern would be visible for a baseline of about 10 m or less, providing a very clean signal of neutrino disappearance into a yet-unknown, "sterile" state. Such a measurement will be free of any reactor-related uncertainties. After 1.5 years of data taking the Reactor Antineutrino Anomaly parameter space will be tested at > 95% C.L.

Firstly, the geo-neutrino flux modeling was reviewed and improved from the point of view of earth sciences. As a consequence, the computational technique to automatically derive the geo-neutrino flux from the seismic topomgraphy data was developed, and the methodology to model the geo-neutrino data that are expected to be accumulated further in the near future, was established. Secondly, the stable geo-neutrino data taking method was developed. Thirdly, the proof of principle experiments of the directionally-sensitive detector were conducted to establish a base technology towards near-future geo-neutrino imaging of the Earth.

A liquid scintillator (LS) detector has a sensitivity of low-energy anti-neutrino. On the other hand, the detector can not measure directional information of anti-neutrino in principle. Development of Li-leaded LS was already complete. Our idea is using fibers to reconstruct a direction of anti-neutrino in Li-loaded LS by measuring light emotion points precisely. We found material which had chemical compatibility and developed a method for processing of fibers. Furthermore, we designed a structure of fibres in Li-loaded LS container and developed prototype detector. We are ready to measure light emotion by radioactive sources using the detector.

<研究目的> 低エネルギー反ニュートリノの到来方向を測定出来る検出器の開発を目指す。 <研究実績> 液体シンチレータによる反ニュートリノ検出は低エネルギーに感度を持つ反面、到来方向の情報を失ってしまう。本研究では^6Liを液体シンチレータに溶かし込むことで中性子捕獲点の決定精度を大幅に向上させることを考えた。更にその反応を位置分解能1cm以上での測定を実現するため、光学レンズと位置検出素子を組み合わせたイメージング検出器を開発する。 ^6Li含有液体シンチレータについては前年度までにほぼ開発を終えることができ、200Lサイズの小型検出器に十分な4.5kgの濃縮^6Li化合物も入手済みである。本年度は開発した液体シンチレータを用いてイメージング検出器の基礎実験を行った。入射窓表面での光のロスが少なく、信号の増幅率も大きい、本研究の使用目的に合った新たなイメージインテンシファイアを購入し基礎実験を行った。開発した^6Li含有液体シンチレータを用い、^<60>Coのγ線を当てて発光位置を再構成したところ目標の位置分解能1.0cmを達成したことを確認出来た。また、本年度は博士論文の研究テーマであった反ニュートリノ信号の研究の為、KamLANDで取得されたデータの解析を行った。原子炉・地球・宇宙起源の各反ニュートリノに対して新たな知見を示し、最終的に3編の論文にまとめて発表した。特に地球反ニュートリノについては地球の放射性物質起源の熱が地熱の約半分程度であるという結果を得る事ができ、ニュートリノを用いた検証という全く新しい方法を確立した。更なる高精度での地球モデルに対する制限を実現する上でも、本研究の方向に感度を持つ検出器の開発は不可欠である。
