Background stability and annual modulation test using PICOLON ultra-pure NaI(Tl) detector
PICOLON Collaboration, K. Kotera, D. Chernyak +20
The dark matter observation claimed by the DAMA/LIBRA experiment has been a long-standing puzzle within the particle physics community. NaI(Tl) crystals with radiopurity comparable…
Present status of PICOLON project
K. Fushimi, D. Chernyak, H. Ejiri +24
The existence of cosmic dark matter and neutrino properties are long-standing problems in cosmology and particle physics. These problems have been investigated by using radiation d…
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…
The nylon balloon for xenon loaded liquid scintillator in KamLAND-Zen 800 neutrinoless double-beta decay search experiment
Zen collaboration, Y. Gando, A. Gando +70
The KamLAND-Zen 800 experiment is searching for the neutrinoless double-beta decay of Xe by using Xe-loaded liquid scintillator. The liquid scintillator is enclosed…
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…
High purity NaI(Tl) scintillator to search for dark matter
Ken-Ichi Fushimi, Hiroyasu Ejiri, Ryuta Hazama +11
A high purity and large volume NaI(Tl) scintillator was developed to search for cosmic dark matter. The required densities of radioactive impurities (RIs) such as U-chain, Th-chain…
Search for Majorana Neutrinos near the Inverted Mass Hierarchy Region with KamLAND-Zen
Zen Collaboration
We present an improved search for neutrinoless double-beta () decay of Xe in the KamLAND-Zen experiment. Owing to purification of the xenon-loaded liquid scintillator…
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…
Measurement of the double-βdecay half-life of ^{136}Xe with the KamLAND-Zen experiment
Zen Collaboration
We present results from the KamLAND-Zen double-beta decay experiment based on an exposure of 77.6 days with 129 kg of Xe. The measured two-neutrino double-beta decay half-l…
