Embodiment Construction
[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0045] The characteristics of the klystron resonant cavity are related to macro performance indicators such as output power and working bandwidth, and the resonant frequency of the resonant cavity is one of its important characteristic parameters. Changing the volume of the resonant cavity can adjust its resonant frequency. The invention provides a frequency continuous tuning device, which is used to adjust the resonant frequency of the resonant cavity of the klystron, so that the klystron can meet the design requirements.
[0046] see Figure 2 to Figure 11 , the first embodiment of the present invention provides a klystron chamber with a frequency continuous tuning device, which includes: a chamber assembly 21 and a cor...

The invention provides a klystron cavity provided with a continuous frequency tuning device and an assembly method thereof. By adopting cooperation between an inner tuning rod assembly, an outer tuning assembly, and a supporting assembly, resonance frequency adjustment can be realized, and space occupied by a tuning assembly is small, and an additional extra device is not required. Good electric contact between a diaphragm and a cavity and high mechanical strength can be guaranteed. A water passage can be cooled, and the heat energy accumulated on the diaphragm can be quickly transferred. A spring is disposed between the inner tuning rod and an inner clamping board, and then the shaking between the inner tuning rod assembly and the outer tuning rod assembly caused by the part cooperation error can be eliminated. The outer wall screw threads of the outer tuning rod and the inner wall screw threads of the fixing screw sleeve are provided with the second screw pitch, and the inner wall screw threads of the outer tuning rod and the long screw rod threads of the inner tuning rod are provided with the first screw pitch, and in addition, the second screw pitch is smaller than the first screw pitch. The accurate control over the deformation quantity of the diaphragm can be realized, and therefore the fine tuning of the cavity resonance frequency can be continuously carried out.
Description
technical field [0001] The invention relates to the technical field of microwave and millimeter wave electric vacuum devices, in particular to a klystron cavity with a frequency continuous tuning device and an assembly method thereof. Background technique [0002] Klystron is a high-power, high-gain and high-efficiency microwave and millimeter-wave amplifier. It also has the advantages of stable and reliable operation and long life, which makes it widely used in scientific research, national defense construction and industrial production. Applications. In the 1940s, due to the development of military radar technology, klystrons made great progress in theory and engineering realization. At the same time, in the field of high-energy physics research, klystrons began to be used to drive electron linear accelerators. power source. Since the early 1950s, with the development of computer technology, through the in-depth analysis of the nonlinear injection wave interaction proces...
