Description
The recent detection of the coherent elastic neutrino-nucleus scattering (CEνNS) opens the possibility to detect neutrinos with small-size detectors and with different techniques, opening a new window to explore possible BSM physics.
The CEνNS process generates signals at the few-keV level, requiring sensitive detection technologies for its observation. The European Spallation Source (ESS) has been identified as the best possible site for the exploration this CEνNS process.
GanESS will use of a high-pressure noble gas time projection chamber to measure CEνNS at ESS in gaseous Xe, Ar and Kr. Such technique appears extraordinarily promising for detecting the process albeit characterization of the response to few-keV nuclear recoils will be necessary.
With this goal, we are currently comissioning GaP, a small prototype capable of operating up to 50 bar. GaP will serve to fully evaluate the low energy response of the technique, with a strong focus on measuring the quenching factor for the different noble gases that will later be used at GanESS.
I will give an overview of GanESS with a focus on the status of GaP and its short-term plans.
