Description
The sensitivity of the direct dark matter search is being improved by various energy-sensitive experiments, such as dual-phase liquid xenon TPCs. In parallel, direction-sensitive dark matter searches are designed and taken place to reveal properties of the dark matter particle after its discovery or to explore beyond the neutrino fog.
NEWAGE is a direction-sensitive WIMP search with a micro-pattern gaseous detector based on the micro pixel chamber (μ-PIC) strip readout, operated at a low gas pressure of 0.1 atm. To further improve the experimental sensitivity, a large-scale detector upgrade is under development. We have developed C/N-1.0, a next-generation detector with an active volume of approximately 1 m³ for future underground dark matter searches at Kamioka Underground Laboratory. The detector is designed to install up to 18 modular detectors. Prior to its underground deployment, we conducted a performance evaluation in a surface laboratory using multiple modular detector units. Using these modular detectors, we confirmed that three-dimensional track reconstruction is feasible in C/N-1.0.
In this talk, we report the results of these detector characterization studies and discuss the readiness of C/N-1.0 for forthcoming underground operation.
