Effect of Dissipation on Excitation of Beam Wave with Negative Energy
Abstract
The effect of dissipation on the instability of overlimiting electron beam caused by excitation of the beam wave with negative energy and transition of this instability to that of dissipative type as the level of dissipation increases is investigated. Growth rates are obtained. The interplay of two effects both leading to excitation of the beam wave with negative energy leads to more critical (as compared with the case of dissipative instability of sublimiting electron beam) dependence of the growth rate on dissipation. An equation describing the influence of dissipation on space-time development of the fields is derived and solved. Analysis of the solution is presented
