Problems solved by technology

In the grid-controlled electron gun without interception, due to the introduction of the control grid, a large number of electrons will be intercepted by the grid, which will affect the electron emission characteristics. Higher precision and stability are required. Therefore, for the reasonable design of the structure of the non-intercepted grid-controlled electron gun, a set of mature non-intercepted grid-controlled electron gun mounting methods and special molds have been explored. important

Embodiment Construction

[0041] Such as figure 1 Shown is a schematic diagram of the structure of a non-intercepting gate-controlled electron gun for a klystron. The mechanical structure of the non-intercepted grid-controlled electron gun is mainly composed of six major components, namely, the cathode heater subassembly 01, the cathode heater support assembly 02, the gate control lead wire assembly 03, the insulating section assembly 04, the beam-focusing pole assembly 05, and the anode assembly 06. see Figure 2a , Figure 2b , the main composition of the grid-controlled electron gun without interception is that the shadow grid 01-01 of molybdenum material is attached to the surface of the spherical barium-tungsten cathode 01-02, and the cathode heater subassembly 01 formed with the heater is fixed on the cathode heater support assembly 02 Above, the molybdenum material control grid 05-01 is fixed in the oxygen-free copper material focusing pole 05-02 to form the focusing pole assembly 05, and a po...

Abstract

The invention, which relates to the technology of an electron gun of a klystron, discloses a method for frame mounting of a non-intercepting gridded electron gun of a klystron. The method comprises the following steps: (a), respectively welding a heater-cathode assembly, a heater-cathode support assembly, a gridded lead assembly, an insulating segment assembly, a buncher assembly, and an anode assembly of an electron gun into a independent part; and (b), positioning, welding, and assembling the six parts in sequence by correlative dies. According to the method provided in the invention, the coaxiality of the frame mounting of the whole electron gun parts is ensured. Compared with a cathode control klystron that is used currently, the non-intercepting gridded klystron, which is constructedby the non-intercepting gridded electron gun assembly by the method provided in the invention, has advantages that an agility of a pulse width and a repetition period is allowed and a flexibility of a wave beam is obtained. Moreover, according to the invention, the radar becomes light and small; current provided by a modulator is reduced and the load of a switching tube is also reduced.

Description

technical field [0001] The invention relates to a mounting method for a grid-controlled electron gun without interception for a klystron. Background technique [0002] In the 21st century, new military revolutions are taking place in the world, and a new round of arms race is going on fiercely. Among them, the detection and guidance radars in the air defense and missile measurement systems of China are in an extremely important position. In order to meet the increasingly complex military needs, research institutions at home and abroad have made it an important goal to develop a radar system with flexible working methods and high mobility. In China, the non-intercept gate control technology is mainly used in traveling wave tubes, and its application in klystrons is still blank. At present, most of my country's existing national air defense radar transmitters use negative-controlled pulse klystrons, especially broadband klystrons, which can achieve perfect frequency agility t...
