LiteBIRD: lite satellite for the study of B mode polarization and inflation from cosmic microwave background radiation detection
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 dr 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 2276 superconducting detectors to measure the frequency range from 40 to 400 GHz with the sensitivity of 3.2 mK*arcmin. including the ongoing studies.
