Progress of Theoretical and Experimental Physics, 2023(4), Nov 21, 2022Abstract LiteBIRD, the Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection, is a space mission for primordial cosmology and fundamental physics. The Japan Aerospace Exploration Agency (JAXA) selected LiteBIRD in May 2019 as a strategic large-class (L-class) mission, with an expected launch in the late 2020s using JAXA’s H3 rocket. LiteBIRD is planned to orbit the Sun–Earth Lagrangian point L2, where it will map the cosmic microwave background polarization over the entire sky for three years, with three telescopes in 15 frequency bands between 34 and 448 GHz, to achieve an unprecedented total sensitivity of $2.2\, \mu$K-arcmin, with a typical angular resolution of 0.5○ at 100 GHz. The primary scientific objective of LiteBIRD is to search for the signal from cosmic inflation, either making a discovery or ruling out well-motivated inflationary models. The measurements of LiteBIRD will also provide us with insight into the quantum nature of gravity and other new physics beyond the standard models of particle physics and cosmology. We provide an overview of the LiteBIRD project, including scientific objectives, mission and system requirements, operation concept, spacecraft and payload module design, expected scientific outcomes, potential design extensions, and synergies with other projects.

Technical report of IEICE. SCE, 113(401) 67-72, Jan 23, 2014We propose a hypothesis that there are a few numbers of quasiparticle states inside the energy gap and analyze the surface resistance and the Q-values of a resonator of superconductor using the hypothesis. The conventional Mattis-Bardeen theory is extended by introducing the complex number of the superconducting gap energy, which well predicts the magnitude of the quasiparticle density of states inside the energy gap. Using the extended Mattis-Bardeen theory, the surface resistance of superconductors and the Q-value of superconducting resonators are calculated. It is shown that simulated temperature dependence of the surface resistance and Q-value of a superconductor agree very well with the experimental results. It is also demonstrated that the calculated residual quasiparticle number of a superconducting resonator using the density of states, which is obtained from the fitting of a dc I-V curve of SIS tunnel junction, quantitatively agrees with the measured one.

Technical report of IEICE. SCE, 113(401) 73-77, Jan 23, 2014Microwave Kinetic Inductance Detector (MKID) camera has been developed at National Astronomical Observatory of Japan for millimeter-wave and terahertz astronomy. MKID composed of superconducting resonators can sense a number of quasi-particles which incident photons above the gap energy generate by breaking Cooper pairs. A bi-layer MKID such as Al/Nb is attractive because the gap energy or the threshold frequency is easily changed due to proximity effect. It is quite useful for space observatory or a remote site such as the Antarctica where power consumption of cryocoolers is severely limited. We report high quality resonators of bi-layer (Al/Nb) MKIDs fabricated by liftoff technique. And we found temperature dependence of bi -layer MKID quality factor showed different behavior as Al or Nb monolayer.

IEICE technical report, 108(100) 117-121, Jun 19, 2008The ALMA (Atacama Large Millimeter Submillimeter Array) is an international project by Europe, North America, and Japan, which is constructing large millimeter and submillimeter array at an altitude of 〜5000m on Atacama desert in northern Chile. The array consisted of 80 high surface accuracy antennae with 12m or 7m diameter extends 14km to achieve 0.01 arc second resolution. Atmospheric windows from 30GHz to 900GHz are covered by 10 frequency bands. We present submillimeter cartridge-type superconducting low noise receivers dictated for ultimate sensitivity. The sensitivity of ALMA is two orders of magnitude larger than those of existing millimeter arrays. The partial operation of ALMA will be started from 2010 and the full operation will be started from 2012.
