| Popis: | The design and experiment of a pulsed Ka-band TE01-mode gyrotron traveling-wave tube are presented. This tube was designed to use the fundamental cyclotron resonance interaction with TE01 cylinder waveguide mode. Backward-wave oscillations of various origins were suppressed by ceramic loading technology. With the electron beam voltage of 66 kV and a beam current of 11 A, a saturated peak power of 110 kW was measured at 33.9 GHz, corresponding to a saturated gain of 34.4 dB, with a −3-dB bandwidth of 1.75 GHz. |
