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…
First reconstruction of absolute three-dimensional position of nuclear recoils using a negative ion -TPC for dark matter search experiments
Satoshi Higashino, Takuya Shimada, Tomonori Ikeda +5
Studies of micro time projection chambers using negative ion gas (NITPC) are conducted especially for direction-sensitive dark matter searches. A NITPC enables to measure the…
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…
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…
Direction-sensitive dark matter search with a low-background gaseous detector NEWAGE-0.3b''
Tomonori Ikeda, Kiseki Nakamura, Takuya Shimada +14
NEWAGE is a direction-sensitive dark matter search using a low-pressure gaseous time projection chamber. A low alpha-ray emission rate micro pixel chamber had been developed in ord…
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…
First limits from a 3d-vector directional dark matter search with the NEWAGE-0.3b' detector
Ryota Yakabe, Kiseki Nakamura, Tomonori Ikeda +13
The first directional dark matter search with three-dimensional tracking with head-tail sensitivity (3d-vector tracking analysis) was performed with a gaseous three-dimensional tar…
Development of a Negative Ion Micro TPC Detector with SF Gas for the Directional Dark Matter Search
T. Ikeda, T. Shimada, H. Ishiura +3
A negative ion micro time projection chamber (NITPC) was developed and its performance studied. An NITPC is a novel technology that enables the measurement of absolute co…
Development of a low--emitting -PIC as a readout device for direction-sensitive dark matter detectors
Takashi Hashimoto, Kentaro Miuchi, Tomonori Ikeda +10
Direction sensitivity could provide robust evidence for the direct detection of weakly interacting massive particles constituting dark matter. However, the sensitivity of this meth…
MPGD simulation in negative-ion gas for direction-sensitive dark matter searches
Hirohisa Ishiura, Rob Veenhof, Kentaro Miuchi +1
Negative-ion time projection chambers (NITPCs) provide the absolute z-position from the arrival-times' difference of several species of negative-ions. This is a strong background r…

Kentaro Miuchi, Tomonori Ikeda, Hirohisa Ishiura +12
A new-concept time projection chamber (TPC) using a commercial resistive sheet, sheet-resistor micro-TPC SR-microPIC, was developed and its performance was measured. SR-microTPC ha…
Development of an alpha-particle imaging detector based on a low radioactivity micro-time-projection chamber
H. Ito, T. Hashimoto, K. Miuchi +5
An important issue for rare-event-search experiments, such as the search for dark matter or neutrinoless double beta decay, is to reduce radioactivity of the detector materials and…
