由于串列加速器的特性,在线同位素分离器产生的放射性核素需转换成负离子才能注入现有的串列加速器。本工作开展了电荷交换器的实验研究,在ISOL离线台架上测量了电荷交换器在不同温度和能量下K+的交换效率。结果发现,在K+能量为9 keV时通过电荷交换器后有60%的离子进行了一次交换,转换成中性的K粒子,有0.7%的K+进行了二次交换,转换成带负电性的K―。实验比较了不同温度下离子的交换效率
Due to the nature of the tandem accelerator, the radionuclides produced by the online isotope separator need to be converted to negative ions to inject into the existing tandem accelerator. In this work, an experimental study on charge exchanger was carried out. The exchange efficiency of K + at different temperatures and energies was measured on the ISOL off-line bench. As a result, it was found that 60% of the ions passed through the charge exchanger at a K + energy of 9 keV were exchanged once, converted into neutral K particles, and 0.7% of K + were exchanged twice to be negatively charged K-. The experiments compared the ion exchange efficiency at different temperatures
