“…Leak tightness is easier to achieve with nitrogen gas and results in a lower cost with respect to the helium configuration. A similar path has been taken by the LBNF project at Fermilab [43].…”

As part of the main focus of the BDF Working Group in 2021, this document reports on the study of alternative locations and possible optimisation that may accompany the reuse of existing facilities with the aim of significantly reducing the costs of the facility. Building on the BDF/SHiP Comprehensive Design Study (CDS), the assessment rests on the generic requirements and constraints that allow preserving the physics reach of the facility by making use of the 4 × 10 19 protons per year at 400 GeV that are currently not exploited at the SPS and for which no existing facility is compatible. The options considered involve the underground areas TCC4, TNC, and ECN3. Recent improvements of the BDF design at the current location (referred to as 'TT90-TCC9-ECN4') are also mentioned together with ideas for yet further improvements. The assessments of the alternative locations compiled the large amount of information that is already available together with a set of conceptual studies that were performed during 2021.The document concludes with a qualitative comparison of the options, summarising the associated benefits and challenges of each option, such that a recommendation can be made about which location is to be pursued. The most critical location-specific studies required to specify the implementation and cost for each option are identified so that the detailed investigation of the retained option can be completed before the end of 2022.

“…This broad program would be addressed using a phased approach, as shown in Table II. Deployment of Theia in the broadband neutrino beam being built for the Long Baseline Neutrino Facility (LBNF) [9,10] would offer excellent sensitivity to neutrino oscillation parameters, including CP violation. Advances in Cherenkov ring imaging techniques lead to improved particle identification and ring counting, which greatly improves background rejection.…”

“…Long-baseline experiments T2K [1] and NOνA [2] operate off-axis in order to enhance the flux of neutrinos at low energies while suppressing backgrounds from higher energies. Theia is designed to operate with high sensitivity in an on-axis neutrino beam (such as the one being designed for the Long Baseline Neutrino Facility (LBNF) [3,4] and the Deep Underground Neutrino Experiment (DUNE) [5][6][7]. Theia will have good sensitivity to neutrino oscillation parameters and neutrino CP Violation (CPV) with a relatively modestly-sized detector.…”

New developments in liquid scintillators, high-efficiency, fast photon detectors, and chromatic photon sorting have opened up the possibility for building a large-scale detector that can discriminate between Cherenkov and scintillation signals. Such a detector could exploit these two distinct signals to observe particle direction and species using Cherenkov light while also having the excellent energy resolution and low threshold of a scintillator detector. Situated in a deep underground laboratory, and utilizing new techniques in computing and reconstruction techniques, such a detector could achieve unprecedented levels of background rejection, thus enabling a rich physics program that would span topics in nuclear, high-energy, and astrophysics, and across a dynamic range from hundreds of keV to many GeV. The scientific program would include observations of low-and high-energy solar neutrinos, determination of neutrino mass ordering and measurement of the neutrino CP violating phase δ, observations of diffuse supernova neutrinos and neutrinos from a supernova burst, sensitive searches for nucleon decay and, ultimately, a search for NeutrinoLess Double Beta Decay (NLDBD) with sensitivity reaching the normal ordering regime of neutrino mass phase space. This paper describes Theia, a detector design that incorporates these new technologies in a practical and affordable way to accomplish the science goals described above. We consider two scenarios, one in which Theia would reside in a cavern the size and shape of the caverns intended to be excavated for the Deep Underground Neutrino Experiment (DUNE) which we call Theia 25, and a larger 100 ktonne version (Theia 100) that could achieve an even broader and more sensitive scientific program.
