57. Status and latest results from CONNIE

Carla Bonifazi (ICAS-ICIFI-UNSAM/CONICET)

Talk

The CONNIE experiment began operating with Skipper-CCDs in 2021, marking the first use of Skipper technology in a reactor neutrino experiment. This technology enables charge measurements with sub-electron resolution, enhancing the ability to detect and characterize low-energy signals. As a result, the experiment achieved a detection threshold as low as 15 eV. Data collected with exposures of...

Talk

Atucha-II is a short baseline neutrino experiment that employs 2.2 g of Skipper-CCD. The detector, installed inside the containment sphere of the 2 GWth Atucha II nuclear reactor at a distance of 12 m from the core, has been operating since December 2021. It currently achieves a readout noise of ~ 0.20 e− by averaging 300 samples of the collected charge in each pixel, with a reactor-OFF...

Talk

The RED-100 is a two-phase noble gas emission detector build for observation of a coherent elastic neutrino-nucleus scattering (CEvNS) in reactor antineutrino interactions with matter. The fist data taking run with LXe target was carried out at the Kalinin nuclear power plant in 2022, and the final results are given. The RED-100 experiment is currently in preparation to the Phase II, with LAr....

6. RELICS: A liquid xenon time projection chamber for CEvNS detection

Shengchao Li (Westlake University)

Talk

The neutrino-nucleus coherent scattering (CEνNS), known as CEνNS, has the largest cross-section among all interaction channels for MeV neutrinos, making it the most promising way to remotely monitor nuclear reactors. A precise determination of the CEvNS cross section has a significant impact on understanding the properties of neutrinos and constraining new physics beyond the standard model....

17. Progress of CryoCsI detector R&D from COHERENT

Chenguang Su (University of Chinese Academy of Sciences)

11/06/2025, 10:28

Talk

This presentation will detail the latest advancements in the development and characterization of a 6.6 kg proto-type CryoCsI detector, comprising two 3.3 kg cesium iodide (CsI) crystals operated at around 90K. Key performance metrics of the detector, including light yield optimization, spatial uniformity of signal response, and long-term stability under sustained cryogenic conditions, will be...
