First measurement of flux of the neutron background induced by accelerated neutrinos at the J-PARC facility
Hiroshi Ito, Ryo Shibayama, Chisako Ise +3
This article reports the measurement of the neutron background flux accidentally induced by the neutrino beam at the J-PARC facility in Japan. In particular, neutrino-nucleus neutr…
Development of a low-background micro pixel chamber for directional dark matter searches
Ryota Namai, Satoshi Higashino, Hirohisa Ishiura +11
Direct detection of weakly interacting massive particles (WIMPs) can provide strong evidence of their existence and the directional method would have an advantage over other method…
Development of a low-background HPGe detector at Kamioka Observatory
K. Ichimura, H. Ikeda, Y. Kishimoto +9
A new ultra-low background high-purity germanium (HPGe) detector has been installed at the Kamioka underground experimental site. The background count rate in the energy range from…
Analyzing the neutron and -ray emission properties of an americium-beryllium tagged neutron source
Hiroshi Ito, Kohei Wada, Takatomi Yano +5
Americium-beryllium (AmBe), a well-known tagged neutron source, is commonly used for evaluating the neutron detection efficiency of detectors used in ultralow background particle p…
Direction-sensitive dark matter search with three-dimensional vector-type tracking in NEWAGE
Takuya Shimada, Satoshi Higashino, Tomonori Ikeda +18
NEWAGE is a direction-sensitive dark matter search experiment with a three-dimensional tracking detector based on a gaseous micro time projection chamber. A direction-sensitive dar…
Search for neutrinos in coincidence with gravitational wave events from the LIGO-Virgo O3a Observing Run with the Super-Kamiokande detector
Kamiokande collaboration, K. Abe, C. Bronner +209
The Super-Kamiokande detector can be used to search for neutrinos in time coincidence with gravitational waves detected by the LIGO-Virgo Collaboration (LVC). Both low-energy ($7-1…
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…
Improved method for measuring low concentration radium and its application to the Super-Kamiokande Gadolinium project
S. Ito, K. Ichimura, Y. Takaku +8
Chemical extraction using a molecular recognition resin named "Empore Radium Rad Disk" was developed to improve sensitivity for the low concentration of radium (Ra). Compared with…
