Current Design of the Electrical Architecture for the Payload Module of LiteBIRD

摘要

LiteBIRD is a space-borne project for mapping the anisotropy of the linear polarization of the cosmic microwave background (CMB). The project aims to measure the B-mode pattern in a large angular scale to test the cosmic inflation theory. It is currently in the design phase lead by an international team of Japan, US, Canada, and Europe. We report the current status of the design of the electrical architecture of the payload module of the satellite, which is based on the heritages of other cryogenic space science missions using bolometers or microcalorimeters.
