摘要: A compact, low cost gyrotron traveling‐wave‐tube (gyro‐TWT) amplifier capable of producing high‐power, broadband, millimeter wave radiation is reported. The interaction circuit a periodic, magnetic field plane (H plane) bend, transverse folded waveguide employed with high‐power axis‐encircling electron beam. Transverse beam modulation and amplification in the gyro‐TWT are observed both linear theory large signal simulations. Calculations from an equivalent model three‐dimensional electromagnetic code predict mode coalescing first stop‐band periodic structure. verified experimental measurements.
