Embodiment 1
[0044] Adopt vacuum sealing radio frequency power coaxial transmission line elbow of the present invention (as figure 1 , 2 As shown), as the coaxial transmission line elbow on the vacuum side of the feed-in window of the RF power coupling feed-in device of the superconducting cyclotron, it can realize the smooth turning of the large RF power on the way to the RF resonant cavity after passing through the feed-in window, that is, Larger RF power is transmitted in bends in a vacuum environment. The main process of its function realization is as follows:
[0045] (1) If figure 1 , 2 , 3, 4, 5, and 6, the outer surface of the inner conductor 2 is concentric with the inner surface of the outer conductor elbow 102, and the relative concentric position between the inner conductor 2 and the outer conductor elbow 102 is determined by the right-angle insulating support 3. The outer threaded ends of 2 pieces of sealing tension rod 402 are screwed into the threaded hole on the outer s...

The invention discloses a vacuum sealing radio frequency power coaxial transmission line elbow, and belongs to the technical field of particle accelerators and radio frequency. The elbow comprises a right-angled outer conductor assembly weldment, a right-angled inner conductor coaxially arranged with the right-angled outer conductor assembly weldment, a right-angled insulating support arranged at a corner between a right-angled outer conductor elbow and the right-angled inner conductor, and vacuum sealing assemblies arranged on each section of cylindrical surface of the elbow of the right-angled outer conductor assembly weldment. The vacuum sealing assembly is combined with the right-angle insulating support, vacuum sealing in the radio-frequency power coaxial transmission line elbow can be achieved, the positions of the inner conductor and the outer conductor can be fixed, and the outer surface of the inner conductor and the inner surface of the outer conductor elbow are concentric. The elbow is high in innovativeness, is especially suitable for a superconducting accelerator radio frequency power coupling feed-in device with a strong leakage magnetic field when a feed-in window is required to be far away from a high-leakage magnetic field region, and has a good practical application value.
Description
technical field [0001] The invention belongs to the fields of particle accelerator technology and radio frequency technology, and in particular relates to a vacuum-sealed radio frequency power coaxial transmission line elbow. Background technique [0002] Many charged particle accelerators or accelerating structures rely on radio frequency electric fields to accelerate charged particles, thereby increasing the energy of charged particles. [0003] The radio frequency electric field is generally generated by the radio frequency transmitter, which is transmitted to the position of the accelerator through the radio frequency power coaxial transmission line, and then the radio frequency power is fed into the radio frequency resonant cavity of the accelerator through the radio frequency power coupling and feeding device, and the radio frequency power resonates in the radio frequency resonant cavity And generate the radio frequency voltage for particle acceleration, which is also ...
