The Fundamental Nuclear and Particle Physics at the ESS workshop
Lund University Fysiska Institutionen
The ESS is presently under construction in Lund, Sweden, and is scheduled to start operating as a multi-disciplinary international laboratory mid-2025. It will eventually be the world’s most powerful pulsed neutron source and simultaneously the worlds brightest pulsed neutrino source. The facility will provide a first neutron moderator, located above the spallation target, designed for high cold and thermal brightness and a second neutron moderator below the spallation target to provide higher intensities, and a shift to longer wavelengths neutrons in the spectral regions of Cold, Very Cold, and Ultra Cold neutrons. Neutrinos will be produced concurrently with the neutrons in the spallation target. In the future the ESS linear accelerator can also be used to produce a long-baseline neutrino beam.
This workshop will bring together the experimental fundamental neutron and neutrino science communities and specialists in all areas of the ESS facility. Brief overviews of the status of current and future experiments will be given, together with the anticipated timelines for reaching the experimental goals. In-depth theory reviews of the physics opportunities will be given, covering experiments using cold and ultra-cold neutrons produced from pulsed neutron sources, experiments exploiting the concurrently produced neutrinos, as well as a potential long-baseline neutrino beam. This will be followed by presentations of proposals for new experiments at the ESS. Presentations from ESS staff scientists will give detailed technical descriptions on the opportunities and the layout of the ESS experimental facilities and there will be plenty of opportunity to interact with ESS staff on the details of realizing the potential experiments.
Proposals for potential experiments at the ESS are being solicited to be presented during the workshop with an emphasis on the scientific impact of the measurement(s) and how it would be integrated into the ESS. The goal of the workshop is to issue a report that summarizes the unique science opportunities of the various proposals put forward by the scientific community for experiments at the ESS. The audience for the report will be ESS management and their advisory bodies, and advisory bodies of other neutron facilities world-wide that host fundamental nuclear and particle physics experiments.
