Dissipative instability under weak beam-plasma coupling
Beam-plasma interaction in waveguide with spatially separated plasma and electron beam is investigated in limit of weak coupling. It is shown that in this case the instability is caused by growing of negative energy beam wave. Dissipation leads to a new type of dissipative beam instability with inverse proportional dependence on dissipation. Growth rate of this instability is obtained for arbitrary level of dissipation.
