Laser ion sources had been being developed at IMP since 2006 due to its enormous potential in the production of high-intensity and high charge state ion beams especially from refractory material.The experiments on the production of multiply charged ions on a laser ion source were carried out in 2012.The charge state distribution of the laser plasma was measured for C,Al and Pb.The schematic diagram of the experimental set-up is shown in Fig.1.A 3JNd∶YAG laser with a pulse duration of 8 ns Laser ion sources had been developed at IMP since 2006 due to its enormous potential in the production of high-intensity and high charge state ion beams especially from refractory material.
