“…The decay-at-rest production results in an intense, pulsed, and isotropic source of neutrinos with energies up to 52 MeV. The planned Proton Power Upgrade (PPU) will increase the SNS proton power on target from 1.4 MW to 2.8 MW by 2028 [12]. This power increase entails a staged 50% increase in the beam current, from 26 to 38 mA; neutrino production will scale linearly with this increase.…”

The COHERENT experiment located in Neutrino Alley at the Spallation Neutron Source (SNS), Oak Ridge National Laboratory (ORNL), has made the world's first two measurements of coherent elastic neutrino-nucleus scattering (CEvNS), on CsI and argon, using neutrinos produced at the SNS. The COHERENT collaboration continues to pursue CEvNS measurements on various targets as well as additional studies of inelastic neutrino-nucleus interactions, searches for accelerator-produced dark matter (DM) and physics beyond the Standard Model, using the uniquely high-quality and high-intensity neutrino source available at the SNS. This white paper describes primarily COHERENT's ongoing and near-future program at the SNS First Target Station (FTS). Opportunities enabled by the SNS Second Target Station (STS) for the study of neutrino physics and development of novel detector technologies are elaborated in a separate white paper.

“…Another approach that has been considered employs a target design which is capable of handling short highpower pulses on the order of 1 µs, similarly to the case at SNS following the Proton Power Upgrade [171]. In such a scenario, the same fast-kicker extraction as for neutrino production, with the same low losses, could be used for the neutron production.…”

A design study, named $${\text {ESS}}\nu {\text {SB}}$$ ESS ν SB for European Spallation Source neutrino Super Beam, has been carried out during the years 2018–2022 of how the 5 MW proton linear accelerator of the European Spallation Source under construction in Lund, Sweden, can be used to produce the world’s most intense long-baseline neutrino beam. The high beam intensity will allow for measuring the neutrino oscillations near the second oscillation maximum at which the CP violation signal is close to three times higher than at the first maximum, where other experiments measure. This will enable CP violation discovery in the leptonic sector for a wider range of values of the CP violating phase $$\delta _{{\mathrm{CP}}}$$ δ CP and, in particular, a higher precision measurement of $$\delta _{{\mathrm{CP}}}$$ δ CP . The present Conceptual Design Report describes the results of the design study of the required upgrade of the ESS linac, of the accumulator ring used to compress the linac pulses from 2.86 ms to 1.2 μs, and of the target station, where the 5 MW proton beam is used to produce the intense neutrino beam. It also presents the design of the near detector, which is used to monitor the neutrino beam as well as to measure neutrino cross sections, and of the large underground far detector located 360 km from ESS, where the magnitude of the oscillation appearance of $$\nu _{e }$$ ν e from $$\nu _{\mu }$$ ν μ is measured. The physics performance of the $${\text {ESS}}\nu {\text {SB}}$$ ESS ν SB research facility has been evaluated demonstrating that after 10 years of data-taking, leptonic CP violation can be detected with more than 5 standard deviation significance over 70% of the range of values that the CP violation phase angle $$\delta _{{\mathrm{CP}}}$$ δ CP can take and that $$\delta _{{\mathrm{CP}}}$$ δ CP can be measured with a standard error less than 8° irrespective of the measured value of $$\delta _{{\mathrm{CP}}}$$ δ CP . These results demonstrate the uniquely high physics performance of the proposed $${\text {ESS}}\nu {\text {SB}}$$ ESS ν SB research facility.

“…The allowed region was shown to shrink by roughly a factor of 2, assuming a reduction in the flux uncertainty from the current 10 % to an uncertainty of 3 %, matching the theoretical uncertainty of the ν e + d cross section. Following this initial program to calibrate the neutrino flux for 1 GeV protons at the SNS, the detector will also be used to calibrate the flux at 1.3 GeV following the SNS Proton Power Upgrade [69]. It will later be moved to the ORNL SNS Second Target Station [70] to further support future neutrino efforts at the SNS.…”

We report on the technical design and expected performance of a 592 kg heavy-water-Cherenkov detector to measure the absolute neutrino flux from the pion-decay-at-rest neutrino source at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL). The detector will be located roughly 20 m from the SNS target and will measure the neutrino flux with better than 5 % statistical uncertainty in 2 years. This heavy-water detector will serve as the first module of a two-module detector system to ultimately measure the neutrino flux to 2-3 % at both the First Target Station and the planned Second Target Station of the SNS. This detector will significantly reduce a dominant systematic uncertainty for neutrino cross-section measurements at the SNS, increasing the sensitivity of searches for new physics.
