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…

Real-time alpha-ray track imaging using a synthetic diamond scintillator
Atsuhiro Umemoto, Masao Yoshino, Takashi Iida +3
We demonstrated real-time imaging of alpha-ray tracks using a high-pressure, high-temperature synthetic diamond scintillator. The optical microscopy system consisted of a magnifica…

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…
