Abstract

In this study we present the results of a directional dark matter search from the NEWAGE experiment. A low-background gaseous detector, namely a low alpha-ray emitting μ-PIC (LAμ-PIC), was developed. The LAμ-PIC was installed in Kamioka Observatory and the NEWAGE-0.3" detector with a detection volume of 37 L was operated from June to November 2018. A total exposure of 1.1 kg•days was obtained and a reduction of background by 30 times comparing with a previous result was confirmed. The remaining backgrounds were studied using a Monte Carlo simulation. The main background in the energy region of 50 ≤ E ≤ 100 keV was found to be alpha-rays emitted from the surface of the LA μ -PIC.
