Embodiment 1

[0035] In this embodiment, a detachable nested composite superconducting cavity is provided. In this embodiment, as Figure 1 to Figure 7 shown, the nested composite superconducting cavity includes:

[0036] At least one superconducting inner cavity 1 is provided, and the superconducting inner cavity 1 is placed in a vacuum environment as a whole; since the superconducting inner cavity 1 is in a vacuum environment as a whole, its interior is a complete vacuum environment, and the outer wall is a vacuum environment, but it is in a vacuum environment. There is no atmospheric pressure difference between the inner and outer walls of the superconducting cavity 1.

[0037] The first non-superconducting shell 2 is provided with a first connection sealing flange 3 at one end, and a first semicircular groove 4 is provided on the inner side of the first connection sealing flange 3;

[0038] The second non-superconducting housing 5 is provided with a second connection sealing flange 6 ...

Embodiment 2

[0047] The disassembled nested composite superconducting cavity provided in this embodiment has basically the same structure as the disassembled nested composite superconducting cavity provided in Embodiment 1, the difference is that the superconducting cavity in this embodiment The number of inner cavities 1 is set to be two or more. In addition to the structure included in Embodiment 1, it also includes at least one double-headed housing 10, such as Figure 8 to Figure 11 shown.

[0048] The double-headed housing 10 is used as a connecting head, and both ends of the double-headed housing 10 are respectively provided with third connecting sealing flanges 11 , the inner side of the third connecting sealing flange 11 is provided with a third semicircular groove 12 , The grooves 12 are respectively matched with the first semicircular groove 4 and the second semicircular groove 7 to form sealed accommodating cavities respectively; each accommodating cavity is provided with a sup...

The invention can be applied to the technical field of radio frequency superconducting.

Description

technical field [0001] The invention relates to the technical field of radio frequency superconductivity, in particular to a detachable nested composite superconducting cavity. Background technique [0002] The radio frequency superconducting cavity is a kind of electromagnetic resonant cavity. Compared with the normal conducting cavity, it has the advantages of high quality factor and high acceleration gradient. It is the core component of the particle accelerator. However, the superconducting materials used in it, such as metal niobium, cost Expensive and difficult to process. Also, the thermal conductivity of superconducting materials is generally low, and decreases with decreasing purity. At the same time, the interior of the superconducting cavity must be evacuated during testing and operation, and the exterior of the superconducting cavity sometimes needs to be placed in atmospheric pressure, and the cavity will withstand a high atmospheric pressure difference. In ord...
