    • An ion manipulation method and device is disclosed. The device includes a pair of substantially parallel surfaces. An array of inner electrodes is contained within, and extends substantially along the length of, each parallel surface. The device includes a first outer array of electrodes and a second outer array of electrodes. Each outer array of electrodes is positioned on either side of the inner electrodes, and is contained within and extends substantially along the length of each parallel surface. A DC voltage is applied to the first and second outer array of electrodes. A RF voltage, with a superimposed electric field, is applied to the inner electrodes by applying the DC voltages to each electrode. Ions either move between the parallel surfaces within an ion confinement area or along paths in the direction of the electric field, or can be trapped in the ion confinement area. A predetermined number of pairs of surfaces are disposed in one or more chambers, forming a multiple-layer ion mobility cyclotron device.
    • 公开了一种离子操作方法和装置。 该装置包括一对基本平行的表面。 内部电极的阵列包含在每个平行表面内并且基本上沿着每个平行表面的长度延伸。 该装置包括电极的第一外部阵列和第二外部电极阵列。 每个外部电极阵列位于内部电极的任一侧上,并且基本上沿着每个平行表面的长度容纳并延伸。 DC电压施加到第一和第二外部电极阵列。 通过向每个电极施加直流电压,将具有叠加电场的RF电压施加到内部电极。 离子在离子限制区域内的平行表面之间或沿着电场方向的路径移动,或者可以被捕获在离子限制区域中。 预定数量的一对表面设置在一个或多个室中,形成多层离子迁移回旋加速器装置。

Ions either move between the parallel surfaces within an ion confinement area or along paths in the direction of the electric field, or can be trapped in the ion confinement area. The surfaces are housed in a chamber, and at least one electrically insulative shield is coupled to an inner surface of the chamber for increasing a mean-free-path between two adjacent electrodes in the chamber.
