在此之前，我们开发了一种α-TOF探测器，用于使用多反射飞行时间质谱仪进行原子质量和放射性同位素衰变性质的相关测量，并成功地展示了重和超重核素的α衰变相关质量测量。在这项工作中，我们开发了一个β-TOF探测器，α-TOF探测器的改进，将这项技术扩展到β衰变核素。81 Ga的在线调试产生了1.44（31）s的测量半衰期，与以前的文献一致，并证实了检测衰变相关事件的效率与立体角限制一致。
Previously, we developed an α-TOF detector for correlated measurements of atomic masses and decay properties of radioactive isotopes using a multi-reflection time-of-flight mass spectrograph, and successfully demonstrated α-decay-correlated mass measurements of heavy and superheavy nuclides. In this work, we develop a β-TOF detector, an improvement upon the α-TOF detector, to extend this technology to β-decaying nuclides. Online commissioning with81Ga yielded a measured half-life of 1.44(31) s, in agreement with the previous literature, and confirmed the efficiency of detecting a decay-correlated event to be consistent with the solid angle limitation.
