- Abstract
- There is a problem in relativistic microwave electronics, namely, how to utilize high currents of relativistic electron beams (REB) with definite electron energy. They manage to utilize electron beams with currents tens times less than the currents of electron accelerators in use at present. The goal of the present work was to demonstrate a possibility to raise the power of microwaves generated by a relativistic plasma maser (RPM) by increasing the electron current when approaching the REB to the waveguide wall. In the present work the regimes of an RPM operation with conventional geometry are compared with other possibilities of mutual positions of the beam and plasma. There are considered as experimental results as and numerical simulation dates.
