Cryogenic readout electronics assembly for the LiteBIRD satellite mission
LiteBIRD is a JAXA-led satellite mission with the goal of performing an all-sky observation of the polarization of the cosmic microwave background (CMB). LiteBIRD's primary science objective is to search for footprints of primary gravitational waves in the CMB, which, if measured, would be a smoking-gun signal of cosmic inflation.
During my PhD at UC Berkeley, I worked on the development of the readout hardware for LiteBIRD. Readout refers to the system which sends, receives and multiplex currents between room-temperature electronics and sub-Kelvin, superconducting detectors. As a graduate student, I was responsible for the first design iterations of the cold-readout sub-assembly, and for the noise characterization of cryogenic electronics used in the readout chain.
