Development of Cosmic Microwave Background (CMB) polarization instruments for LiteBIRD

Details of research theme

LiteBIRD is an international mission to measure the polarization in the cosmic microwave background (CMB) through the all-sky survey to reveal the presence of the primordial gravitational wave predicted by the inflation theory. LiteBIRD has been selected as JAXA strategic large mission in the 2020s. LiteBIRD observes 34-448 GHz with wide field millimeter-wave telescopes and the 0.1K detectors. The successful candidates will conduct research and development related to the mission instruments on board LiteBIRD, which include the low-frequency telescope, low noise detection systems, cooling systems, data processing, ground tests of the instruments, and system engineering. He/She will also conduct basic development research to be applied to the future CMB instrument as his/her individual research. We will foster researchers who deeply understand mission instruments and can lead the future missions in the field of space astronomy and astrophysics.

Required abilities, qualities, and experience

It is preferable to have knowledge and experience in one of the following items: (1) development of telescopes and/or detectors for space usage; (2) development of low-noise detectors operated at low temperature; (3) development of millimeter-wave instruments; (4) optical design or measurement; (5) experimental studies in the field of fundamental physics, (6) study of systematic errors on the CMB observations.

Research environment after arriving at one’s post.

The successful candidates can get support in conducting research from the professors who are members of the LiteBIRD team and have a lot of experience in the development of instruments and promotion of space missions. If needed, the candidates can also get support from other professors at ISAS. There are basic and advanced facilities necessary to conduct the research; examples are an 100mK cryostat, a millimeter-wave precision measurement system and software packages to study system engineering.
