Nevodovskij P. Application of photoelectronic receivers of radiation with arsenite - gallium - indium photocathodes for spectropolarimetris observations of planets

The dissertation is devoted to the implementation in the astronomical spectropolarimetric observations of new photo multipliers with InGaAs - photocathodes, for study the gas component of planetary atmospheres. The cooling photometric head on the base of photo multipliers with InGaAs was developed, investigated, and its working parameters were optimized for research of astronomical objects in a wide spectral range (340 - 1070 nm). The results of basic characteristics and parameters of photo multipliers ФЭУ-79, ФЭУ-157 with InGaAs photocathodes are obtained. The analysis and comparison of the obtained results was carried out. The recommendations for the creation of cooling photometric heads on the basis of the photo multiplier with InGaAs-photocathodes are presented. The results of full-scale tests of a complex ASP-1 demonstrate the efficiency of our equipment for study of weak astronomical objects in a wide spectral range. The results of spectrofotopolarimetri of observations the Jupiter are presented.
