摘要： PROBLEM TO BE SOLVED: To measure the kinetic energy of a charge particle of ion or the like with high resolution by using an orbit in which multiple circulation is possible. SOLUTION: The orbit is formed as the primary position and primary angle of ion converge in time but the kinetic energy of ion does not converges in time every when ion circulates two times using a plurality of troidal electronic fields E1 and E2. A high ion transmittance is realized by converging ion in space in every two circulations in horizonal plane including the orbit without depending on the primary position, primary angle or primary kinetic energy, and by making the orbit that does not disperse even in vertical plane. Thereby, the flight time becomes depend only on the kinetic energy, and more the ion circulated the orbit the more the energy resolution increased. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：通过使用可以进行多次循环的轨道，以高分辨率测量离子等的电荷粒子的动能。解决方案：轨道形成为离子的主要位置和主角在时间上收敛，但是当使用多个细胞电场E1和E2离子循环两次时，离子的动能不会随时间收敛。通过在包括轨道的水平平面的每两个循环中的空间中会聚离子而不依赖于主要位置，初级角或初级动能，以及即使在垂直平面中也不分散的轨道，实现高离子透射率。因此，飞行时间仅取决于动能，并且更多的离子循环轨道，能量分辨率增加得越多。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To enable ionic mobility analysis with suppressed diffusion of ions in a radial direction without reducing permeability of low-mass ions, by a simple configuration.SOLUTION: An ionic mobility separation device comprises: an electrode unit 1 consisting of an electrode group surrounding a drift region; and a controller applying voltage to the electrode group to form an acceleration electric field in a center axis direction in the drift region. An incident ion group is moved in a buffer gas of the drift region by the electric field. The electrode unit includes: 2n (n≥2) pole electrodes 2 extending over front and rear ends of the drift region and arranged around the center axis; and a plate-like electrode group 3 arranged respectively between adjacent pole electrodes. Each set of the plate-like electrode group includes a plurality of plate-like electrodes OEk arranged in the center axis direction so as to be separated from each other, and oriented in parallel with a surface including the center axis. A high-frequency voltage having a phase different by 180 degrees from the adjacent pole electrodes is applied to the pole electrodes. Such a DC voltage that there is a constant potential difference between the plate-like electrodes adjacent in the center axis direction is applied to the plate-like electrode group to form the acceleration electric field.
