HIRFL-CSR accelerator facility has been operating with 3 ion sources,which are LAPECR1,LECR3 and SECRAL.These ion sources can provide different kinds of ions with different energy.For example,LAPECR1 mainly provides H+and He+with eextraction voltage above 25 keV,LECR3 can provide the ion beams with low to medium charge states,including the metallic ions with low mass,such as C^4+,Ar^11+,B^3+,Mg^7+,etc.,while SECRAL aims to produce intense and highly charged ion beams,especially metallic ones,such like Kr^19+,Xe^31+,Ni^19+,Bi^31+,U^33+,and so on.
