Abstract :
A study of the electrodynamical properties of gyrotron coaxial cavities using a conical inner rod has been conducted and compared with cold-test measurements on TE modes over the frequency range 11-14 GHz. On the basis of a geometrical design criterion for resonance of the normal modes, it has been demonstrated that the mode spectrum associated with a purpose-built test coaxial cavity is significantly less dense than that for the empty cavity without the coaxial insert
