Mechanism of radiation pulse shortening in plasma relativistic microwave generator
Tóm tắt
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.
