Myroshnichenko Valentyn I.
Corresponding Member of NAS of Ukraine, Senior research assistant, Honored Scientist of Ukraine
Valentyn Myroshnichenko is a famous physicist in the field of charged particle beams and plasma electronics, was born on 21 May 1935, Ivanivka village, Vovchan district, Kharkiv region, Ukraine. He graduated from the Kharkiv State University in 1958. From 1958 to 1995 he rised from junior researcher to the head of laboratory in the Kharkiv Institute of Physics and Technology. From 1995 to present he is the head of electrostatic accelerator department, Institute of Applied Physics NAS of Ukraine. Also, he is a deputy director of the Institute since 2006.
Valentyn Myroshnichenko is the author of pioneer works on relativistic electron beams to be used for generation of a short-wave electromagnetic radiation while interaction with electromagnetic waves based on forced coherent scattering of these waves by electrons of relativistic beam. He was the first, together with american scientists, to develop non-linear theory of free electron laser operation in so-called Raman mode when electron Langmuir oscillations in relativistic beam occured due to the influence of ponderomotive force of incident and scattered waves become essential.
It was found an experimental verification of his prediction concerning amplification of amplitude coefficients of a short-wave radiation when interaction is in the presence of external magnetic field under the fulfillment of resonance conditions. He is a co-author of idea and development of non-linear theory of plasma-loaded free electron laser for the case when undulator is a Langmuir wave excited in plasma.
In this work a new joint mechanism of Langmuir wave scattering, so-called abnormal scattering, was found. Note, that a year later an article of a big group of american authors where the same ideas were presented and considered, was published.
V. I. Myroshnichenko together with Ya. B. Fainberg are the authors of idea and non-linear theory on physical mechanism of electron beam acceleration based on reverse mechanism of plasma-loaded free electron laser .
His pioneer work devoted to study of non-stability during ion-cyclotron heating of ion component of plasma served as a beginning of a wide range of theoretical and experimental works carried out in KIPT while solving problems of controlled nuclear fusion. Scientific achievements of V. I. Myroshnichenko of the last decades are related to design and construction of IAP analytical accelerator facility to study elemental composition and structure of substances with nuclear physics techniques.
These investigations and developments resulted in a start-up of the first on the territory of CIS nuclear scanning microprobe to carry out non-destructive local analysis of structure and elemental composition of substances.
V.I. Myroshnichenko actively participates in training of young specialists working as a professor of experimental and theoretical department and where he gives courses "Physical principles of charged particle acceleration" and "Physics of plasma".
