Radiative decay of muonic molecules in resonance states
Takuma Yamashita, Kazuhiro Yasuda, Yasushi Kino
In this study, we theoretically investigated x-ray spectra from the radiative decay of muonic deuterium molecules in resonance states dd, which plays an important role in a…
Radiopurity of NaI(Tl) crystals for PICOLON dark matter experiment
K. Kotera, D. Chernyak, H. Ejiri +19
The dark matter observation claim by the DAMA/LIBRA collaboration has been a long-standing puzzle within the particle physics community. Efforts of other research groups to verify…
PICOLON dark matter search project
K. Fushimi, D. Chernyak, H. Ejiri +21
PICOLON (Pure Inorganic Crystal Observatory for LOw-energy Neutr(al)ino) aims to search for cosmic dark matter by high purity NaI(Tl) scintillator. We developed extremely pure NaI(…
Dark matter search with high purity NaI(Tl) scintillator
K. Fushimi, Y. Kanemitsu, K. Kotera +21
A dark matter search project needs and extremely low background radiation detector since the expected event rate of dark matter is less than a few events in one year in one tonne o…
Development of highly radiopure NaI(Tl) scintillator for PICOLON dark matter search project
K. Fushimi, Y. Kanemitsu, S. Hirata +20
The highly radiopure NaI(Tl) was developed to search for particle candidates of dark matter. The optimized methods were combined to reduce various radioactive impurities. The $^{40…
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) with…
Dark matter search project PICO-LON
K. Fushimi, H. Ejiri, R. Hazama +12
The PICO-LON project aims at search for cold dark matter by means of highly radio-pure and large volume NaI(Tl) scintillator. The NaI powder was purifed by chemical processing to r…
WIMPs search by exclusive measurements with thin multilayer NaI(Tl) scintillators (PICO-LON)
K. Fushimi, H. Kawasuso, K. Yasuda +11
The WIMPs search project PICO-LON has been started with multilayer thin NaI(Tl) crystals. The thin (0.05cm) and wide area (5cmx5cm) NaI(Tl) crystals was successfully developed. The…
Multi-layer scintillation detector for the MOON double beta decay experiment: Scintillation photon responses studied by a prototype detector MOON-1
H. Nakamura, P. Doe, H. Ejiri +50
An ensemble of multi-layer scintillators is discussed as an option of the high-sensitivity detector Mo Observatory Of Neutrinos (MOON) for spectroscopic measurements of neutrino-le…
The performance of thin NaI(Tl) scintillator plate for dark matter search
K. Fushimi, H. Kawasuso, E. Aihara +12
A thin (0.05cm) and wide area (5cmX5cm) NaI(Tl) scintillator was developed. The performance of the thin NaI(Tl) plate, energy resolution, single photoelectron energy and position s…
