Description
The $\nu GeN$ experiment is a research project aimed at exploring the properties of neutrinos [1]. The experiment is being conducted at the Kalinin nuclear power plant (KNPP) in Udomlya, Russia. The experimental setup is positioned $11.1-12.2 m$ from the reactor core under the third unit of the KNPP. This unique location provides a high flux of antineutrinos, ranging in $3.6 - 4.4 × 10^{13} ν/(cm^{2}s)$, and shielding equivalent to $\sim 50 m$ of water equivalent, ensuring favorable background conditions.
The main goal of the $\nu GeN$ experiment is to study rare processes, such as coherent neutrino scattering, in order to search for the neutrino's magnetic moment and other unusual phenomena. A specially designed high-purity germanium (HPGe) detector, weighing $1.4 kg$, with a low background value and a low threshold, is used for this task. The detector is surrounded by a combined shielding system, incorporating active and passive components to protect against external background sources.
During the experiment, the spectrometer demonstrated stable performance, achieving an efficiency of over $80\%$ for signals above $250 eV$. To date, more than $1600 kg-days$ of data have been collected, providing a solid foundation for the ongoing analysis.
