Solid target disassembling device and method Technical Field The invention relates to the technical field of medical isotope production, in particular to a solid target disassembling device and method. Background Medical radioisotopes find wide application in medical diagnostics and therapy. The natural radionuclides present in nature are of few species, so most medical radioisotopes are manufactured artificially, such as accelerator production, reactor production and isotope generator production. Wherein the high energy beam generated by the accelerator can be used for obtaining target nuclides by bombarding various targets. Targets are generally classified into solid targets and liquid targets. The solid target material ensures that the target material and the copper support form a target piece as a whole in a mode of welding the target material and the copper support, and ensures that the target material and the copper support are tightly attached to each other, so that the target material is cooled by utilizing good heat conductivity of copper and circulating cooling water. However, in the process flow of preparing medical isotopes, it is very important to dissolve and extract the required isotopes from the irradiated target, and the integrity of the target disassembled from the copper holder will directly affect the yield of the finally extracted isotopes.
