Abstract :
The efficiency of powerful gyro-devices strongly depends on the quality of helical electron beams (HEBs) used as an active media for RF generation. The most popular system to form HEB is the magnetron-injection gun (MIG). In MIGs one of the most important factors influencing on the quality of HEBs is the reflection of particles from the magnetic mirror near the cavity. Influence of the pulse form U(t) on the establishing process in HEB is performed. The case when HEB has big pitch-factor and so trapped electrons influence on the beam parameters essentially is considered.
