The COHERENT experiment, located at the Spallation Neutron Source at Oak Ridge National Laboratory, has now made first measurements of CEvNS on three nuclear targets: CsI, Ar, and Ge. A NaI detector has begun taking data. New detectors and detector upgrades are addressing backgrounds and systematics across all COHERENT measurements: CEvNS, inelastic neutrino-nucleus scattering, and dark-matter...

P-type Point Contact (PPC) High-Purity Germanium detectors have been a popular choice for CEvNS searches due to their sub-keV energy thresholds and kg-scale masses. Recently, the COHERENT Collaboration constructed Ge-mini: an 18-kg array of Inverted-Coaxial Point Contact (ICPC) PPC detectors. In this talk we will discuss the design, construction and performance and operation of the Ge-mini...

The CONUS experiment was operated inside an optimized shield at the Brokdorf nuclear power plant which provided a reactor antineutrino flux of up to 2.3*10^13/(cm^2 s). The talk will cover the latest results including the final phase of data collection at this site in comparison to the rate predicted by the Standard Model. The talk will also cover limits on new physics which can be derived...

The first detection of coherent elastic neutrino nucleus scattering (CEvNS) at a nuclear reactor remains to be achieved, especially because the corresponding nuclear recoils lie in the O(100 eV) energy regime which is difficult to measure with conventional detection technologies, and also because of the unfavorable background conditions nuclear power plant environments generally offer. To...

The Mitchell Institute Neutrino Experiment at Reactor (MINER) experiment at the Nuclear Science Center at Texas A&M University is searching for coherent elastic neutrino-nucleus scattering within close proximity (2-5 meters) of a 1 MW TRIGA nuclear reactor core using phonon mediated low threshold solid state detectors . Given the Standard Model cross section of the scattering process and the...

The CONUS+ experiment is a new project which aims to detect coherent elastic neutrino-nucleus scattering (CEνNS) of reactor antineutrinos on germanium nuclei in the fully coherent regime, continuing in this way the CONUS physics program. After refurbishment, the four 1 kg point-contact high-purity germanium detector operate at significantly improved energy thresholds and resolutions. In...

The Scintillating Bubble Chamber (SBC) collaboration is designing and building a bubble chamber to search dark matter and measure coherent elastic neutrino-nucleus scattering utilizing argon as a target material. The bubble chambers excel as exceptional detectors for uncovering rare events like neutrino interactions, owing to their insensitivity to electron recoils and capability to reject...

We will present the latest physics and detector R&D results and plans on the pursuit of neutrino nucleus elastic scattering at the Kuo-Sheng Reactor Neutrino Laboratory in Taiwan, with sub-keV germanium ionization detectors [1]. This includes recent efforts in quantifying and studying the quantum-mechanical coherency effects of the interactions [2,3]. Future possibilities to continue and...

The RICOCHET reactor neutrino observatory aims at measuring the coherent elastic neutrino-nucleus scattering (CEνNS) of antineutrinos at the Institut Laue-Langevin, ILL (Grenoble, France). To that end, RICOCHET employs two cryogenic calorimeter technologies : one based on germanium targets with neutron-transmutation-doped thermistors (the CryoCube) and one based on superconducting targets and...

The CONNIE experiment aims to detect CEvNS of reactor antineutrinos off silicon nuclei using thick fully-depleted high-resistivity silicon CCDs. In 2021, two Skipper-CCD sensors with sub-electron readout noise capability were installed at the experiment next to the Angra-2 reactor, marking CONNIE as the first experiment to employ Skipper-CCDs for reactor neutrino detection. Thanks to the...

In this study, we conducted a comprehensive characterization and optimization of a cryogenic pure CsI (pCsI) detector. Achieving a notable light yield of 35.2PE/keVee and a world-leading energy resolution of 6.9% at 60keV, we utilized a 2cm cubic crystal coupled with a HAMAMATSU R11065 photomultiplier tube (PMT). Additionally, we measured the scintillation decay time of pCsI, which proved to...

The first experimental measurement of coherent elastic neutrino-nucleus scattering (CEνNS) was successfully conducted using a CsI(Na) scintillation crystal detector. Recognizing that a higher light yield in scintillation crystal detectors correlates with greater physical sensitivity for CEνNS detection, we introduced a novel low-temperature CsI detector design employing SiPMs readout. This...

Ricochet is an experiment based at the Institut Laue-Langevin (ILL) reactor in Grenoble aimed at detecting coherent elastic neutrino-nucleus scattering. Ricochet is designed to be a milliKelvin platform supporting multiple technologies, each differentiating between electronic recoils, nuclear recoils, and heat-only events. One such technology —CryoCube— uses an array of germanium crystals,...

For over 53 years, it was predicted that the neutrino, the smallest particle in the universe, is capable of splitting the atom. This phenomenon of neutrino-induced nuclear fission, or nuFission, is a portal between the weak and strong interactions and may lead to a new method for nuclear reactor monitoring. However, before these use cases can be leveraged, the central question must be meted...

Prof. Xiang Xiao (Sun Yat-sen University (China))Talk
The coherent elastic neutrino-nucleus scattering (CEνNS) channel stands out among all interaction channels for MeV neutrinos from nuclear reactions due to its large cross-section. However, detecting CEνNS poses significant challenges, particularly in lowering the energy threshold while mitigating the background. The RELICS experiment is proposed to use the liquid xenon time projection chamber...
