摘　　要：镱同位素在放射性药物、原子钟、核物理等领域具有重要应用。电磁法是目前可用于分离镱同位素的最佳选择,为了收集和监测电磁法分离后的镱同位素,本文研制了镱同位素束流接收与监测系统。针对镱同位素分离色散小、数目多、不易分离的特点,通过理论计算和经验参数,设计多缝面板、内置水冷结构的模块化收集器和束流监测系统,减少同位素的蒸发和溅射,提高镱同位素的丰度。最终完成镱同位素束流接收与监测系统测试,目前该系统已经应用于镱同位素的分离,镱-176同位素丰度达到96.9%。Ytterbium isotopes have important applications in radiopharmaceuticals,atomic clocks,nuclear physics and other fields.Electromagnetic method is the best choice for the separation of ytterbium isotopes.In order to collect and monitor the ytterbium isotopes separated by electromagnetic method,a ytterbium isotope beam receiving and monitoring system is developed.According to the characteristics of ytterbium isotope separation,such as small dispersion,large number and difficult separation,a modular collector with multi slit panel and built-in water cooling structure and a beam monitoring system were designed through theoretical calculation and empirical parameters.The evaporation and sputtering of isotopes were reduced and the abundance of ytterbium isotopes was improved.Finally,the test of ytterbium isotope beam receiving and monitoring system was completed.At present,the system has been applied to the separation of ytterbium isotopes,and the ytterbium 176 isotope abundance has reached 96.9%.
