Ratan-600 'cosmological gene' project
Abstract
We present some details of the new generation RATAN-600 CMBA project and estimate an efficiency of the 'near field zone' mode of ground based experiments in atmospheric noise filtration as well as in instrumental polarization effects. It is shown that with big enough aperture the sensitivity of the ground-based and space based CMBA experiments can be close to each other. Ground based experiments are not limited in resolution even at low frequencies boundary of the 'Galaxy window', and we suggest using RATAN-600 as a pre-PLANCK probe of possible Galaxy contamination for future mission, and as a post-PLANCK facility for very deep CMBA polarization experiments. This project may help to interpret deeply PLANCK mission results.
