摘要
大型同位素电磁分离器真空室在大气压力作用下会出现严重的内凹现象。本文利用数值模拟方法,分析了内凹对磁场分布和离子束聚焦特性的影响,指出了一条消除内凹影响的有效途径。
The vacuum chambers of large-scale electromagnetic isotope separstors (Calu-trons) are of serious inward-concavity under the atmospheric pressure. The nume-rical simulation method is used to analyse the effect of inward-concavity on themagnetic field distribution and ion beam focussing characteristics. It is pointedout that strengthening the magnetic induction and adjusting the position of recei-ver adequately for a constructed apparatus can eliminate the effect of inward-concavity on the image widths of beams. This idea is verified through adjustmentof an electromagnetic isotope separator.
