Abstract: New developments in liquid scintillators, high-efficiency, fast photon detectors, and chromatic pho-ton sorting have opened up the possibility for build-ing a large-scale detector that can discriminate betweenCherenkov and scintillation signals. Such a detector couldreconstruct particle direction and species using Cherenkovlight while also having the excellent energy resolutionand low threshold of a scintillator detector. Situateddeep underground, and utilizing new techniques in com-puting and reconstruction, this detector could achieveunprecedented levels of background rejection, enablinga rich physics program spanning topics in nuclear, high-energy, and astrophysics, and across a dynamic rangefrom hundreds of keV to many GeV. The scientific pro-gram would include observations of low- and high-energysolar neutrinos, determination of neutrino mass order-ing and measurement of the neutrino CP-violating phaseδ, observations of diffuse supernova neutrinos and neu-trinos from a supernova burst, sensitive searches fornucleon decay and, ultimately, a search for neutrino-less double beta decay, with sensitivity reaching thenormal ordering regime of neutrino mass phase space.This paper describesTheia, a detector design that in-corporates these new technologies in a practical and af-fordable way to accomplish the science goals describedabove.
