我们报告的气体喷射运输系统耦合到一个表面电离离子源的JAEA-ISOL（同位素分离器在线）系统的发展。作为用于气体喷射系统的新的气溶胶材料，具有713 °C的低沸点的CdI 2被利用来防止气溶胶材料在离子源表面上的沉积。一个额外的灯丝是新安装在以前的离子源，以提供均匀加热的离子发生器。本系统可用于测量核反应中产生的各种短寿命镧系元素同位素的绝对效率。
We report on development of a gas-jet transport system coupled to a surface ionization ion-source in the JAEA-ISOL (Isotope Separator On-Line) system. As a new aerosol material for the gas-jet system, CdI2, which has a low boiling point of 713 °C, is exploited to prevent deposition of the aerosol material on the surface of the ion-source. An additional filament is newly installed in the previous ion-source to provide uniform heating of an ionizer. The present system is applied to the measurement of absolute efficiencies of various short-lived lanthanide isotopes produced in nuclear reactions.
