Popis: | The causes of emission quenching in the plasma relativistic microwave generator are studied by numerical calculations using the particle-in-cell method. The process mechanism in which the plasma boundary moves from the coaxial collector edge with a velocity above 107 cm/s is found. An electron flux with an energy of ∼105 eV and a current of ∼103 A is generated from the collector in the formed gap, which heats plasma and increases its potential. Microwave generation stops due to a multiple decrease in the wave reflectance from the collector. The use of the hollow collector is presumably a method for preventing microwave generation quenching. |
