Abstract :
Based on the dispersion equation of electromagnetic mode and the nolinear theory of gyrotron traveling wave amplifier (gyro-TWA), the influence of the thickness of the lossy layer on beam-wave interaction in the gyro-TWA is studied. The bandwidth decreases with the increase of the thickness, but the output power of the middle of the bandwidth increase and becomes more smoothly by appropriately choosing the thickness and conductivity of the lossy layer. It´s useful to improve the stability of gyro-TWA.
