Description
The paleo detector is new approach for rare event search in astroparticle physics such as dark matter. The mica is good candidate for the paleo detector because of its cleavage, transparency and relatively low threshold of track formation to the energy deposition due to particles.
In this study, we are focusing on the Q-ball. The Q-ball is non-topological soliton in the early universe, and it is important theoretical model for the baryogenisis, beyond standard model and dark matter. And, the Q-ball can have electric charge, therefore the mica is expected to detect that as long tracks.
In this talk, current status of detector calibration using ion beam, evaluation of the detection performance and optical scanning system will be reported, and discuss about future subjects and physics case.
