一般注記The frequency characteristics of the gyrotron FU-IV in free running mode are examined precisely using heterodyne mixing technique. First, the frequency characteristics are measured and the short-term spectral bandwidths and the drifts of the center frequency are found to be less than 10 kHz full width at half maximum and about 10 MHz during 20 min, respectively. Next, an effective water-cooling system reduced the drifts of the center frequency within a range of several MHz. Then, the frequency, the cooling-water temperature, the beam current and the output power are monitored simultaneously to examine the relationship among these parameters. The results indicate that the beam current drift correlate with the frequency drift due to frequency pulling effect as well as the thermal expansion and contraction of the resonant cavity.
