| Abstract: | We present the results of the experiments on a continuous-wave gyrotron with an output frequency of about 260 GHz, which has
been developed for dynamic polarization of nuclei and is operated at the second cyclotron-frequency harmonic. For an accelerating
voltage of 16 kV and a beam current of 0.3 A, a maximum continuous-wave radiation power of about 200 W has been obtained.
Measurements of the thermal load on the resonator cavity allow evaluating its actual ohmic Q-factor. Gyrotron radiation is
also observed at other frequencies and modes. Their generation zones and the structure of the output radiation have been studied.
Long-term stability of gyrotron parameters has been determined. |
