The observed shape was clearly different from the shape of scintillation light. The pulse rise and fall (decay) time for Cherenkov light were 0.8 ns and 2.5 ns, respectively. They were actually shorter than those times of scintillation light which were also measured by 1.6 ns and 6.5 ns, respectively. This clear Thisclearclear difference of rise time will be used for the pulse shape discrimination in order to select PMTs which receive Cherenkov lights, and the topological information due to Cherenkov light will be used for the reduction of backgrounds from 208Tl beta decay which should be major backgrounds observed around Q-value (3.35MeV)of 96Zr neutrinoless double beta decay.}, pages = {169--176}, title = {Precise pulse shape measurement of Cherenkov light using sub-MeV electrons from Sr-90/Y-90 beta source}, volume = {54}, year = {2020} }
