Abstract :
In this work, new results obtained in the course of antenna-amplifier development are reported. These are the results of PIC simulations using the 3-D version of the MAGIC code and studies concerning the possibility of plasma formation at the dielectric rod surface located within the annular beam. The latter studies include theoretical consideration of the device slow-wave structure with a plasma layer near the rod surface and model experiments on beam transport in the guide magnetic field with the rod inside, aimed at estimating the plasma density
