heal.abstract	We discuss the possibility of a proof-of-principle experiment regarding the excitation of a high-order mode interacting with the electrons at the second harmonic of the cyclotron frequency in a coaxial gyrotron cavity with a longitudinally corrugated inner conductor. The experiment will employ the 2MW -170 GHz coaxial gyrotron for ITER at Forschungszentrum Karlsruhe, Germany, which is designed to operate with the TE34,19 mode at the fundamental cyclotron frequency. Our study suggests that by using about half the magnetic field and modifying the coaxial cavity to a reasonable extent, the TE 34,19 mode (or some other mode of similar eigenvalue) can be excited at 170 GHz as a second-harmonic mode. © 2004 IEEE.	en
