为研究中能重离子轰击天然Pb厚靶生成的较短寿命的Hg同位素产物,研制成功一套带有跑兔系统的气相热色谱分离装置。它可自动进行靶辐照并可实现Hg产物快速脱出、分离和收集。收集的样品被传送到低本底测量站而不破坏真空。利用此系统可分离半衰期为20s或更短一些的核素。
In order to study the Hg isotope product with shorter lifetime generated by heavy ion bombardment of natural Pb thick target, a set of gas-phase thermal chromatographic separation device with running rabbit system was successfully developed. It automatically irradiates the target and allows rapid removal, separation and collection of Hg products. The collected samples are sent to a low background measurement station without damaging the vacuum. Use this system to separate radionuclides with a half-life of 20s or less.
