Submillimeter and millimeter wave sky mapping in the space project submillimetron

摘要

Submillimetron is an international project of the space telescope for astronomical studies at submillimeter and millimeter wavelengths using free-flying spacecraft and facilities of the Russian segment of the International Space Station. The payload is the 60-cm telescope cooled to liquid helium temperature with arrays of a novel type detector, Normal-metal Hot-Electron Bolometer (NHEB). The angular resolution is 1-10 arcmin, field of view - about 1 degree, detectors sensitivity - about 10{sup}(-18) W/Hz{sup}(1/2), spectral region - 0.2-2 mm. Parameters of the instrument and complementarity to other experiments including CMB measurements are discussed.
