Our group is performing an experiment called POLARBEAR, which is aiming at the discovery of the B-mode polarization of cosmic microwave background (CMB). From the CMB, we can obtain information about the inflation of the early universe, mass of the neutrino, etc.
　Currently the experiment is being conducted at Atacama in Chile, and an upgrade project to the POLARBEAR-2 is underway. I would like to contribute to the development of the upgraded receiver with my experience in experimental particle physics.
