共振空胴がある）。In the resonance cavity structure of the conventional klystron as described above, the central axis of the hole 3 for adjusting the resonance frequency of the fine tuner is the resonance cavity as described above. It was common to match the axial centerline of 1. However, when used in a klystron with a high operating frequency, the height of the resonant cavity 1 becomes low, so the inner diameter of the hole 3 had to be made small (in the X band 100 MW pulse klystron, H 1 = 3 mm). There is a resonant cavity).
