Low background measurement in CANDLES-III for studying the neutrino-less double beta decay of Ca
S. Ajimura, W. M. Chan, K. Ichimura +65
We developed a CANDLES-III system to study the neutrino-less double beta (0) decay of Ca. The proposed system employs 96 CaF scintillation crystals (305 kg) wi…
FerroHEMTs: High-Current and High-Speed All-Epitaxial AlScN/GaN Ferroelectric Transistors
J. Casamento, K. Nomoto, T. S. Nguyen +11
We report the first observation of ferroelectric gating in AlScN barrier wide-bandgap nitride transistors. These FerroHEMT devices realized by direct epitaxial growth represent a n…
A Next-Generation Liquid Xenon Observatory for Dark Matter and Neutrino Physics
J. Aalbers, K. Abe, V. Aerne +591
The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leadi…
A study on energy resolution of CANDLES detector
B. T. Khai, S. Ajimura, W. M. Chan +20
In a neutrinoless double-beta decay () experiment, energy resolution is important to distinguish between and background events. CAlcium fluoride for studies of N…
The energy calibration system for CANDLES using (n, γ) reaction
T. Iida, K. Mizukoshi, T. Ohata +28
CAlcium fluoride for the study of Neutrinos and Dark matters by Low-energy Spectrometer (CANDLES) searches for neutrino-less double beta decay of Ca using a CaF scintill…
TCA DAQ system and parallel reading in CANDLES experiment
B. T. Khai, S. Ajimura, K. Kanagawa +5
A new TCA DAQ system was introduced in CANDLES experiment with SpaceWire-to-GigabitEthernet (SpaceWire-GigabitEthernet) network for data readout and Flash Analog-to-Digital Con…
