It is shown that an electrostatic field structure including a local wedge field in the area of small ion kinetic energies, followed by a planar accelerating field, allows to efficiently vary and control the inclination angle of time fronts (isochronous surfaces) in essentially parallel ion beams. When combined with deflectors, wedge fields allow independent control of the trajectory inclination angle and of the time front inclination angle. Two particular applications of local wedge fields are shown for improvement of planar multi-reflecting time-of-flight (MR-TOF) analyzers. One is a combination of an orthogonal accelerator and a deflector arranged for dense folding of ion trajectories. The other is a combination of an ion mirror and a deflector for reversing the ion motion and elongation of the flight paths.

结果表明，静电场结构包括小离子动能区域中的局部楔形场，然后是平面加速场，允许有效地改变和控制基本平行离子束中时间前沿（等时表面）的倾角. 当与偏转器结合使用时，楔形场允许独立控制轨迹倾角和时间前倾角。显示了局部楔形场的两个特殊应用，用于改进平面多反射飞行时间 (MR-TOF) 分析仪。一种是正交加速器和偏转器的组合，用于离子轨迹的密集折叠。另一种是离子镜和偏转器的组合，用于反转离子运动和飞行路径的伸长。
