Nonproportional Response of a GAGG Scintillator to Beta and Gamma Radiation over a Wide Energy Range in PIKACHU
Takumi Omori, Takashi Iida, Yosuke Suga +12
Nonproportional response of scintillation light yield for sub-MeV radiations is a well-known characteristic of inorganic scintillators. In the PIKACHU experiment, a precise underst…
Simulation Tool Development and Sensitivity Analysis of 160Gd Double Beta Decay Search by the PIKACHU Project
Takumi Omori, Takashi Iida, Nobuo Hinohara +11
Neutrinoless double beta decay (0v2b) has been investigated as a physical process that can provide evidence for the Majorana nature of neutrinos. The theoretical predictions of the…
Combined Pre-Supernova Alert System with Kamland and Super-Kamiokande
KamLAND, Super-Kamiokande Collaborations, : +311
Preceding a core-collapse supernova, various processes produce an increasing amount of neutrinos of all flavors characterized by mounting energies from the interior of massive star…
First Study of the PIKACHU Project: Development and Evaluation of High-Purity GdGaAlO:Ce Crystals for Gd Double Beta Decay Search
Takumi Omori, Takashi Iida, Azusa Gando +8
Uncovering neutrinoless double beta decay (02) is crucial for confirming neutrinos' Majorana characteristics. The decay rate of 0 is theoretically uncertain, influe…
