### Description

The recent detection of the coherent elastic neutrino-nucleus scattering (CE$\nu$NS) opens the possibility to use neutrinos to explore physics beyond standard model with small size detectors. However, the CE$\nu$NS process generates signals at the few keV level, requiring of very sensitive detecting technologies for its detection. The European Spallation Source (ESS) has been identified as an optimal source of low energy neutrinos offering an opportunity for a definitive exploration of all phenomenological applications of CE$\nu$NS. In this project, we propose to apply the high pressure gas Time Projection Chamber (TPC) technology to the detection of the CE$\nu$NS process at the ESS. This will require the development of very low-energy detectors and the improvement of the current knowledge of the quenching factor for nuclear recoils in gas at keV energies. The major goal of this project is to build a compact noble gaseous detector (~20 kg) compatible with different nuclei such as xenon, argon or krypton in the same set-up with minimal increase in the cost and operate it at the ESS. Such detector will provide more than 7,000 CE$\nu$NS events per year, overtaking the sensitivities of much larger detectors in current spallations sources.
