About an overview of LiteBIRD overview、please see the image (we are sorry that descriptions are in Japanese there).
The basic concept of LiteBIRD follows:
- 1) Design a satellite optimized for the observation of large-scale (>degree) CMB B-mode polarization.
- 2) Design a reasonably light and small satellite to maximize the chance for launch.
Major specifications follow:
|Observation duration||3 years|
|Orbit||Sun–Earth L2 (LEO as an option)|
|Cooling system||Similar to SPICA (no cryogen) with ST/JT combination and ADR to have the base temperature of 0.1K.|
|Focal-plane detector||Superconducting detector array (TES or MKID) with about 2000 sensors|
|Sensitivity||2 micro-Kelvin x arcmin|
|Observing frequencies||6 bands between 50 and 320 GHz|
|Modulation||Satellite spin and half-wave-plate modulation|
