AI Technical Summary

Problems solved by technology

[0008] Analyzing the above research status, it is not difficult to see that the research on the L-band relativistic Cerenkov oscillator has made great progress, but there are the following deficiencies: five slow-wave blades are usually used, and the axial length is relatively long, resulting in the guide The magnetic field is long, which is not conducive to the miniaturization of devices; the power conversion efficiency is usually around 30%, and the energy conversion efficiency of the system is low

[0009] Therefore, although people have begun to study compact L-band relativistic Cerenkov oscillators, few mature and simple solutions have been seen, especially the technical solutions for simultaneously realizing light, small and high-efficiency devices have not yet been disclosed. report
