DEVYATKOV, NIKOLAI DMITRIEVICH (Electronic Engineer) 



N. D. Devyatkov was born April 11, 1907. He graduated 

 from the Leningrad Polytechnical Institute in 1931. In 1925 he 

 worked at the U.S.S.R. Academy of Sciences Physico -Technical 

 Institute and subsequently in a number of other scientific re- 

 search institutes. In 1954, he became head of a scientific re- 

 search institute and also the Department of Ultra -High Frequen- 

 cy Electronics at the U.S.S.R. Academy of Sciences Institute of 

 Radio Engineering and Electronics. Since 1944 he has been 

 teaching at the Moscow Institute of Energy. He became a 

 Corresponding Member of the U.S.S.R. Academy of Sciences in 

 1953. 



Devyatkov has studied the gaseous discharge, the con- 

 struction of gaseous discharge devices for protecting lines of 

 communication from over voltage and acoustic shock, and also 

 gaseous discharge devices for modulated radiation in the infra- 

 red part of a spectrum. He has worked out ultra high frequency 

 devices for detecting, generating and converting frequencies of
