Embodiment Construction
[0015] refer to figure 1 , represents the schematic diagram of the heterosexual plug. ΦD1 and ΦD3 represent the inner diameter and outer diameter of the opposite sex plug, respectively, and ΦD2 represents the initial diameter of the tapered slope. refer to figure 2 , represents the schematic diagram of a notched copper sheet. L2 in the figure is the gap width.
[0016] The feature of the present invention is to utilize several groups of different size plugs of the opposite sex (the plugs of the opposite sex are annular, and the taper changes from the inner ring to the outer ring, and the ring is equally divided into two half rings, such as figure 1 shown), when there are 5-6 magnetic rings remaining in the assembly of the magnetic system, insert the plugs into the pole pieces to replace the unassembled magnetics, replace the corresponding plugs according to the degree of tightness of the whole system, and install the plugs The dimensions determine the difference between t...

The invention relates to a helix traveling wave tube magnetic focusing system assembly method which belongs to the field of microwave vacuum electronic devices. Along the direction of a helix traveling wave tube axis, magnetic rings and pole pieces are periodically and alternatively lined into a focusing system length; semi-circular heterogeneous patches corresponding to the size of the magnetic rings serve as transitional patches; the heterogeneous patches are inserted between the pole pieces in parallel with the direction of the spacing between the magnetic rings to replace unassembled magnetic disks; and the corresponding heterogeneous patches are replaced according to the tightness of the whole set of system, the number of required copper sheets or the total thickness of the ground magnetic disks are calculated, and the copper sheets with gaps are put between the assembled magnetic rings and the pole pieces. After a magnetic system is assembled through the method, the internal electronic through rate of the devices is improved.
Description
technical field [0001] The invention belongs to the field of microwave vacuum electronic devices, in particular to a method for adjusting and assembling a magnetic focusing system of a helical traveling wave tube. Background technique [0002] The magnetic focusing system of the helical traveling wave tube is composed of a certain number of parts such as pole shoes, connecting sleeves and magnetic rings that are set outside the shell of the traveling wave tube. Among them, the pole shoe is set outside the shell of the traveling wave tube; the connecting sleeve is used as a part to support the magnetic ring to ensure the concentricity between the outer diameter of the shell and the inner diameter of the magnetic ring. It can be placed on the shell or divided into two halves. Then assemble it together with the magnetic sheet. The magnetic ring is first divided into two halves, and is installed between two adjacent pole pieces after the exhaust process is completed. The pole ...
