The invention relates to a liquid-helium-free radio frequency superconducting accelerator. Charged particle beams flow through an injection system to be generated and led out and are led into an acceleration module through a beam transmission system, a power source system provides radio frequency power for the acceleration module, low level and a control system are used for monitoring operation, and the amplitude and phase of an electromagnetic field in a superconducting cavity are kept stable. and after being accelerated in the acceleration module, the charged particles are introduced into the application terminal through the beam transmission system. The superconducting cavity is cooled in a solid conduction mode, so that the superconducting cavity stably operates at low temperature, charged particle beams are accelerated, the cooling mode that a current radio frequency superconducting accelerating cavity can only be soaked in liquid helium is eliminated, a liquid helium soaking cooling thermostat with a complex structure and a liquid helium low-temperature station with high manufacturing cost and large occupied scale are omitted, the accelerator also has the advantages of low price, small occupied area, simple structure, compact layout, convenience in operation and maintenance and the like, the application difficulty of the radio frequency superconducting accelerator can be remarkably reduced, and the application range of the radio frequency superconducting accelerator is greatly expanded.
Description
technical field [0001] The invention relates to a superconducting accelerator, in particular to a liquid helium-free radio frequency superconducting accelerator based on solid conduction cooling, and belongs to the technical field of superconducting. Background technique [0002] Charged particle accelerators are indispensable research tools in the fields of high energy physics, atomic and molecular physics, life and material science, nuclear physics and radionuclide research. Thanks to the extremely low surface resistance of the radio frequency superconducting accelerating cavity (superconducting cavity), compared with room temperature accelerators, superconducting accelerators have the advantage of being able to work in high duty cycle or even continuous wave mode. Radio frequency superconducting is a modern particle accelerator one of the core technologies. [0003] Superconducting cavities are the core accelerating components of superconducting accelerators. At present...
