Creation of a unique set of the spectral and polarization complex of high resolution in the range of 6-18 GHz, consisting of 64 channels with a 1% analysis stripe was concluded. Based on the combination of key parameters - the frequency overlap and resolution, sensitivity and accuracy of polarization measurements, such a complex is the first instrument of its kind in the practice of solar astronomy.
A new cryogenic radiometer with the sensitivity close to the limit on the surface of the Earth was developed, manufactured and implemented for normal observations at the RATAN-600. The radiometer operates at the dedicated frequency for the radio astronomy, 4.8 GHz (6.25 cm), uses both modes of circular polarization with a separate amplifier channel for each mode, and implements an additional gain in sensitivity owing to the absence of losses due to the splitting of circular modes in the aperture of the RATAN-600.
