摘要: To improve spatial and energy acceptance of multi-reflecting time-of-flight, open traps, electrostatic trap analyzers, a novel ion mirror is disclosed. Incorporation immersion lens between mirrors allows reaching the fifth order time per focusing simultaneously with third including energy-spatial cross terms. Preferably analyzer has hollow cylindrical geometry for extended flight path. The time-of-flight preferably incorporates spatially modulated field isochronous in tangential direction.
