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…

First Study of the PIKACHU Project: Development and Evaluation of High-Purity Gd $_{3}$ Ga $_{3}$ Al $_{2}$ O $_{12}$ :Ce Crystals for $^{160}$ Gd Double Beta Decay Search

Takumi Omori, Takashi Iida, Azusa Gando +8

Uncovering neutrinoless double beta decay (0 $ν$ 2 $β$ ) is crucial for confirming neutrinos' Majorana characteristics. The decay rate of 0 $ν β β$ is theoretically uncertain, influenced…
