重复使用能量-等熵飞行时间质谱仪中的飞行路径，由于总的长飞行距离，可以实现非常高的质量分辨能力。除了它们的纵向等时性之外，这样的系统可以提供高的横向相空间接受度，使得它们可以利用大相空间体积的离子束。这可以通过类似于加速器存储环设计中使用的技术从匹配的单位单元构建系统来实现。
Using the flight path in an energy-isochronous time-of-flight mass spectrometer repeatedly, one can achieve very high mass resolving powers because of the overall long flight distance. Additionally to their longitudinal isochronicity, such systems can provide a high transversal phase-space acceptance so that they can make use of ion beams of large phase-space volumes. This can be achieved by building the system from matched unit cells similarly to the techniques used in the design of accelerator storage rings.
