Description
This presentation will discuss the possibility of starting a program in fundamental physics at the European Spallation Source, under construction on Lund, with a specific focus on neutrino physics. One the one hand some experimental aspects of starting a program based on Decay-at-Rest (DAR) neutrinos that are produced in the ESS spallation target without any further adjustments of the facility itself will be presented. The specific challenge, when using DAR neutrinos for experiments that rely on Coherent elastic neutrino-nucleus scattering (CEvNS), is the need to reach very low-energy thresholds for detection of the nuclear recoil. A few different technologies for such experiments will be presented with a focus on low-noise and low-threshold HPGe detectors for CEvNS experiments. In the second part of the presentation I will show some results from the now completed Conceptual Design Report of a possible long-baseline neutrino facility at the ESS, ESSnuSB, funded by the EU via the Horizon 2020 program and also touch on the work done in the follow-up project ESSnuSB+.
