We did some preliminary tests on LECR3 to produce Silicon and Chlorine ion beams in October 2003. Some good results have been achieved. Some useful conclusions have been drawn from those experiments. And afterwards, we also provided the HIRFL accelerator with the 35C112+ ion beam for the nuclear physics experiments.For the productions of Silicon and Chlorine ion beam, materials like SiH4, SiCl4 and CCl4 are chosen as the test samples. The typical characteristics of these materials are listed in Table 1. We did some preliminary tests on LECR3 to produce Silicon and Chlorine ion beams in October 2003.
