Search for coherent elastic neutrino-nucleus scattering with RED-100 detector
Abstract
The RED-100 (Russian Emission Detector) is constructed for search of coherent elastic neutrino-nucleus scattering (CEvNS) off atomic nuclei. This fundamental process was predicted several decades ago by the Standard Model of electroweak interactions but has not been discovered yet. The RED-100 is an emission two-phase xenon detector containing ~200 kg of liquid Xe (~ 100 kg in a fiducial volume). The detector description is given covering principle of operation, technical details and current status. Future plans for detector deployment at the experimental site are presented.

Summary

The RED100 detector is built to search for coherent elastic neutrino-nucleus scattering (CEvNS) off atomic nuclei. This process was predicted by the Standard Model but has never been observed yet. The RED-100 is an emission two-phase xenon detector containing ~200 kg of liquid Xe (~ 100 kg in a fiducial volume). The RED100 experimental setup consists of several systems that provide stable and effective operation. These systems are the detector itself located inside a shielding, cryogenics, purification, light collection, electronics and data acquisition. The detector principle of operation and design are described.The current status of the RED100 detector is discussed as well. Future plans for the detector installation at a neutrino source are given.
