Description

technical field [0001] The invention relates to the technical field of ion accelerator superconducting cavity processing, in particular to a chemical buffer automatic polishing system and method for the entire cavity surface of a superconducting cavity. Background technique [0002] After the superconducting cavity is processed, the inner surface of the cavity must be polished. To achieve the purpose of chemical buffer polishing, it is necessary to develop a system that can realize the polishing operation, and at the same time need to have the corresponding polishing medium. Since the superconducting cavity chemical polishing process uses a highly toxic and highly corrosive mixed acid solution, the equipment developed must fully consider the safety of the operator and the equipment. In addition, the equipment also needs to strictly control the flow, velocity, temperature, pressure and time of the acid liquid during work, so the equipment must have strong corrosion resistance...
