摘要： A magnetron is configured so that an antenna lead 17 connected to a desired position of an anode segment 2 passes through a magnetic pole piece 7 and a metal cylinder 8 so as not to make contact therewith and is connected to the output portion of the magnetron, and so that the electrical length L1 of this antenna lead 17 between the opening end of a third harmonic restraint choke 15 and the connection portion of the anode segment 2 is 1/2 of the wavelength (λ) of the third harmonic, thereby restraining the third harmonic and the side bands of the third harmonic.

摘要： In each anode vane 10, there is provided the brazing material spreading prevention groove 13 that interconnects the strap ring inserting portions 11 and 12 in parallel to the direction of the central axis Ax. With such a configuration, it is possible to prevent the residual brazing material 3a from spreading to the front end part 10a of the anode vane 10 when each anode vane 10 is brazed on the inner peripheral surface of the anode cylinder 1. Therefore, non-uniformity in thickness of the anode vanes 10 caused by the residual brazing material 3a is suppressed, and electrostatic capacity between the anode vanes 10 adjacent to each other becomes substantially constant. Thus, it is possible to obtain stable resonant frequency. In addition, it becomes easy to perform adjustment for obtaining the stable resonant frequency in that non-uniformity in initial frequency of the time when the magnetron is completely assembled decreases.
摘要翻译：在每个阳极叶片10中，设置有与环带插入部分11和12平行于中心轴线Ax的方向互连的钎料扩散防止槽13。通过这样的结构，当阳极叶片10钎焊在阳极筒1的内周面上时，可以防止残留钎焊材料3a向阳极叶片10的前端部10a扩散。因此，由残留钎焊材料3a引起的阳极叶片10的厚度均匀性被抑制，并且彼此相邻的阳极叶片10之间的静电容量变得基本恒定。因此，可以获得稳定的谐振频率。此外，变得容易进行调整，以获得稳定的谐振频率，因为磁控管完全组装时的初始频率的不均匀性降低。

摘要： A magnetron includes: an anode cylinder including anode vanes provided at a predetermined interval on an inner peripheral surface thereof; a center lead including a first linear portion, a second linear portion disposed parallel to the first linear portion and disposed out of alignment with the first linear portion in a plane perpendicular to an axial direction of the anode cylinder, and a bent portion which connects the first linear portion to the second linear portion; and a cathode filament supported by the center lead within the anode cylinder and placed coaxially with the anode cylinder. The center lead is formed so as to become bent between the first linear portion and the second linear portion by the bent portion. A position of one anode vane closest to the bent portion is higher than a position of another anode vane with respect to the axial direction.
