在重离子储存环中建立的等离子体质谱（IMS）中，储存的二次离子的旋转时间应与其速度扩散无关。然而，这种等熵条件仅在一阶和小范围的旋转时间内满足。为了校正非等时性，需要对每个存储离子的速度或磁刚度进行额外的测量。为此目的，两个新的飞行时间（TOF）探测器安装在兰州CSRe实验冷却储存环的直线段。新的飞行时间（TOF）检测器的性能，这是至关重要的可实现的效率和质量分辨率，显着提高。离线测试中TOF探测器的时间分辨率为σ= 18.5±2 ps。探测器装置以78 Kr的稳定束流投入运行。
In isochronous mass spectrometry (IMS) established in heavy-ion storage rings the revolution times of the stored secondary ions should be independent of their velocity spread. However, this isochronous condition is fulfilled only in first order and in a small range of revolution times. To correct for the non-isochronicity an additional measure of the velocity or magnetic rigidity of each stored ion is required. For this purpose two new time-of-flight (TOF) detectors were installed in a straight section of the experimental Cooler Storage Ring CSRe in Lanzhou. The performance of the new time-of-flight (TOF) detectors, which is crucial for the achievable efficiencies and mass resolving power, was significantly improved. The time resolution of the TOF detector in offline tests was σ= 18.5±2 ps. The detector setup was put into operation with a stable beam of 78 Kr.
