Main directions of research

The Department of Physical Electronics was created by Academician of the Russian Academy of Sciences G.A. Mesyats on 3 November 2004. The Department was organized in accordance with the decision of the LPI Scientific Council on the expediency of developing works on coherent sources of microwave radiation, high-power nanosecond electronics, high-temperature physics and controlled thermonuclear fusion; of developing plasma devices and solving problems of high- current pulsed power engineering at the Physical Institute. The Department of Physical Electronics is headed by Academician of the Russian Academy of Sciences G.A. Mesyats. The Department consists of two laboratories.

The Laboratory of Vacuum and Plasma Electronics is at present headed by the Corresponding Member of the Russian Academy of Sciences N.A. Ratakhin. Main directions of work of the Laboratory: 

  • studies of ectonic processes in electric discharges
  • development of a pulsed accelerator of electrons for a wide-aperture femtosecond petawatt laser
  • formation and transport of dense electron beams
  • studies of the properties of matter in extreme states.
The Laboratory of Pulsed Processes headed by the Corresponding Member of the Russian Academy of Sciences M.I. Yalandin carries out studies of fast electric-discharge and commutation processes, oriented to the development of high-power small-size generators of nano- and picosecond voltage and electromagnetic radiation pulses. The main directions of work are related to studies of the dynamics of ectonic processes in high-current accelerator diodes:
  • analysis of the physical processes leading to degradation of the emission properties of nonheated cathodes under conditions of high peak and average powers of electron beams formed
  • studies of the frequency constraints of the effect of polishing of explosion-emission graphite cathodes
  • studies of the dynamics of formation of a picosecond electron beam in the diode gap in transition from vacuum to gas insulation.

Research at the Department of Physical Electronics of the Lebedev Physical Institute is carried out within the framework of the goal-oriented complex program of the Presidium of the Russian Academy of Sciences and is supported by grants of the Russian Foundation for Basic Research. Studies are performed in cooperation with departments of the Institute of Electrophysics, Ural Division of the Russian Academy of Sciences and the Institute of Hig-current Electronics, Siberian Division of the Russian Academy of Sciences.
