NEWAGE is a direction-sensitive dark-matter-search experiment that uses a micro-patterned gaseous detector, or {mu}-PIC, as the readout. The main background sources are {alpha}-rays from radioactive contaminants in the {mu}-PIC. We have therefore developed a low-alpha-emitting {mu}-PICs and measured its performances. We measured the surface {alpha}-ray emission rate of the {mu}-PIC in the Kamioka mine using a surface {alpha}-ray counter based on a micro TPC.
Direction sensitivity could provide robust evidence for the direct detection of weakly interacting massive particles constituting dark matter. However, the sensitivity of this method remains low due to the radioactive backgrounds. The purpose of this
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 order to reduce background for dark matter search. We conducted the dark
The known direction of motion of dark matter particles relative to the Earth may be a key for their unambiguous identification even in the presence of backgrounds. We describe a prototype detector that is able to reconstruct direction vectors of weak
A direction-sensitive dark matter search experiment at Kamioka underground laboratory with the NEWAGE-0.3a detector was performed. The NEWAGE- 0.3a detector is a gaseous micro-time-projection chamber filled with CF4 gas at 152 Torr. The fiducial volu
We have carried out the dark matter search with a 116g direction-sensitive stilbene crystal in Kamioka Observatory. With the crystal fixed to the earth, we searched the modulation of thelight output. No modulation signal was found due to the small si
