基于重离子储存环的等离子体质谱是直接测量短寿命核质量的有力工具。由于高能反应产物的飞行分离的性质,许多具有不同质荷比()的离子种类可以一次性传输到环中并存储在环中。然而,高质量分辨能力可以实现只有一个有限的范围内的离子物种的速度很好地匹配的环的等离子条件。需要了解每个存储离子的速度以克服这种限制。为此,两个飞行时间(TOF)探测器安装在一个直线段的冷却器储存环CSRe在兰州相隔18米。由两个TOF探测器测量的每个存储离子的时间序列用于精确确定其速度。对于单个离子,速度的相对精度达到了.在数据中清楚地确定了环中离子运动的电子感应加速器振荡,并在分析中加以考虑。所提出的技术可用于测量机器的曲调和它们对粒子动量的依赖。
Isochronous mass spectrometry based on heavy-ion storage rings is a powerful tool for direct mass measurements of very short-lived nuclei. Owing to the nature of in-flight separation of high-energy reaction products, many ion species with different mass-to-charge ratios () can be transmitted to and stored in the ring in one shot. However, high mass resolving power can be achieved only for a limited range of ion species with velocities well matching the isochronous condition of the ring. The knowledge of velocities of each stored ions is required to overcome this restriction. For this purpose, two time-of-flight (TOF) detectors were installed 18 m apart in one straight section of the cooler-storage ring CSRe in Lanzhou. The time sequences measured by the two TOF detectors for each stored ion were used for the precision determination of its velocity. A relative precision of the velocity is achieved to the level offor individual ions. The betatron oscillations of the ion motion in the ring were clearly identified in the data and were taken into account in the analysis. The presented technique can be used for measurements of machine tunes and their dependence on particle momenta.
