である。As for magnetrons, coaxial magnetrons, which combine every other resonator of an anode resonator system with a coaxial cylindrical cavity, have excellent performance in terms of mode separation, frequency stability, efficiency, etc., but they have a large structure. Since it is complicated and has drawbacks such as difficulty in cooling the anode resonator system, it is unsuitable for use in aircraft or rockets, which require particularly small size and light weight.

設計する必要があり、共振器のＱを下げる欠点がある。Conventional so-called multi-segmented anode magnetrons are suitable for making magnetrons smaller and lighter; however, strapping structures add capacitance to each anode resonator, making the resonator relatively small ( (lower inductance)
However, it has the disadvantage of lowering the Q of the resonator.
一方ライジングサン構造のものは、１個おきの共振器系

周波数の共振系とで構成され、比較的共振器を大きくで
きるので、共振器のＱ低下は防止できるが、高精度の加
工を要し、共振周波数の微調整が難しいという欠点を有
している。On the other hand, in the rising sun structure, every other resonator system is composed of a resonant system with a frequency higher than the oscillation frequency by a certain amount and a resonant system with a lower frequency, which allows the resonator to be relatively large. Although Q reduction can be prevented, it requires high-precision machining and has the disadvantage that fine adjustment of the resonance frequency is difficult.
