Abstract:

The instabilities in system consisting of electron beam and spatially separated dissipative plasma is investigated in details. A study is developed that allows carrying out the investigation in general form, independently on system geometry, specific parameters, external fields etc. It only is assumed slight overlapped of the beam and the plasma fields (so-called weak beam-plasma coupling). In this case the beam-plasma interaction significantly differs from conventional case of full overlap (strong coupling). Under weak coupling the role of the beam proper oscillations becomes decisive. The instability is due to growth of the beam negative energy wave. With increase in level of dissipation the instability turns to a new, up to recently unknown type of dissipative instability.
