摘要：

LiteBIRD is a next generation satellite aiming for the detection of the Cosmic Microwave Background (CMB) B-mode polarization imprinted by the primordial gravitational waves generated in the era of the inflationary universe. The science goal of LiteBIRD is to measure the tensor-to-scaler ratio r with a precision of delta r < 10(-3), offering us a crucial test of the major large-single-field slow-roll inflation models. LiteBIRD is planned to conduct an all sky survey at the sun-earth second Lagrange point (L2) with an angular resolution of about 0.5 degrees to cover the multipole moment range of 2 <= l <= 200. We use focal plane detector arrays consisting of 2622 superconducting detectors to measure the frequency range from 40 to 400 GHz with the sensitivity of 2.5 mu K.arcmin. We report an overview and the status of the project, including the ongoing studies.
