An off line test setup was built at Tsinghua University,Beijing. Initial experimental results indicate that carrying neutral Na monoatoms to the He jet outlet and then using laser resonant ionization of Na atoms in the He jet beam are very efficient. This provides a highly efficient method for producing Z selected ions with low background and short delay time. This method is useful in the separation of various elements, particularly, refractory elements.展开更多
