Description

technical field [0001] The present application relates to but not limited to the field of electromagnetic separation, in particular to a high-efficiency vacuum-pumped isotope electromagnetic separation system. Background technique [0002] As the demand for isotope production capacity increases, the support of isotope separation methods is needed. Commonly used isotope separation methods include gas diffusion, centrifugation, and electromagnetic methods. Compared with other separation methods, the electromagnetic method has good versatility. It can separate almost all elements on the periodic table. It is the only feasible method to obtain isotopes such as Rb and Yb. The isotope separation mode is currently the best choice for the preparation of high-abundance isotopes. [0003] At present, traditional electromagnetic separation systems such as figure 1 As shown, it includes ion source 01, ion 02, vacuum chamber 03 and receiver 04. The ion 02 emitted by the ion source 01 i...

AI Technical Summary

Problems solved by technology

If the vacuum degree does not meet the specified requirements, there will be two adverse effects: 1) The ion source will frequently break down the air and cause abnormal discharge, making the separation unstable

2) The ion beam collides with the air, which affects its original trajectory, resulting in a decrease in the abundance and yield of separated isotopes

The volume of the vacuum chamber of the separator is generally 2 to 5 cubic meters, and such a large volume of space is pumped from atmospheric pressure to 3×10 -3 Pa, time-consuming and labor-intensive, which seriously restricts the operating efficiency of the electromagnetic separator
