Abstract:
Multi-reflection time-of-flight (MR-ToF) devices are established as mass separators and analyzers with high resolving powers and fast processing times. For ion injection and ejection, either the ion mirrors or an in-trap lift electrode has to be switched. In the present work, these two methods are combined with in-trap lift switching for ion capture and exit-side mirror switching for ejection with higher information content. Measurements are performed with small lead clusters to illustrate individual advantages of both techniques and the gain of combining them with focus on the ions' ToF ejection window.
