镱同位素电磁分离束流接收与监测系统研制

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%。

Research and Measurement of Synchrotron Radiation System for HLS

The paper introduces the synchrotron radiation system for Hefei Light Source (HLS),which includes the streak camera system,the bunch length system using photoelectric method,the beam profile measurement system,and the photon beam position measurement system.The bunch length and bunch lengthening were measured using the streak camera system and the photoelectric method.The beam profile measurement system was used to observe the suppression effects of sextupole on beam transverse instability and the feedback effects of the transverse bunch-by-bunch feedback system.The photon beam position measurement system used two wire-type monitors and the logarithmic signal processor,which was used to detect the beam motions.
