英文摘要: The investigation of the key technologies of ion source for radioactive ion beam generation based on nuclear reactor will be carried out.The key technolodies include:the working mechnism of the ion source will be investigated to make the efficiency of ion source high enough to ionization the rare radioactive species;the structure of the ion source will be investigated to fit the ion source into size limited neutron channel of reactor and solve the high voltage isolation problem between the ion source and the neutron channel.The character of ion source's temperature will be investigated to make sure that the heat from target in ion source can be carried away from the ion source safely and the materials of the ion source can work at about 2300 degree temperature .The configuration of extraction system will be investigated so that the extraction electrodes and its following beam transport elements can be fit into the size limited neutron channel.
