Abstract
In the present work, the quality factor of the Gyrotron tube as a function of cavitythe diameter and lengthwas studied. Attenuation coefficients as a function of both frequency (GHz) and cavity radius was also studied. A computer program was costructed and designed for compute the quality factor and attenuation coefficients for only TEmnl modes. The same program calculates the cut off frequencies of the lowest order modes. Results shows good agreement with experimental and theoritical studies.
