This paper is devoted to the noisetron creation history in 1967 – the chaotic oscillations oscillator consisted of two traveling wave tubes (TWT), contacted successively in ring. It is shown that the noisetron creation is the result of the work on HF noise generation in the systems electron-ion plasma–electron stream, which was fulfilled in V.Ya. Kislov’s laboratory. This work was initiated by the theoretic investigations on the interaction of electron stream with electron-ion plasma, fulfilled by V.Ya.Kislov in the period of 1956...1960 years.
