研究了新型傅里叶变换离子回旋共振（FT-ICR）池中离子的运动。该电池设计由一个圆柱形静电阱和一个用于在ICR电池内部创建势阱的内部导线组成。离子池被建模为轴向磁场中的Kingdon阱。给出了理论描述，并讨论了使用这种细胞（线离子导向细胞）设计的优点。给出了使用细长的金属丝离子导向单元（纵横比= 3.3）和小的地效玻璃单元（纵横比= 1）确定影响捕获性能的参数的实验结果。
Ion motion in a novel Fourier transform ion cyclotron resonance (FT-ICR) cell design is investigated. The cell design consists of a cylindrical electrostatic trap and an inner wire used to create a potential well inside the ICR cell. The ion cell is modeled as a Kingdon trap in an axial magnetic field. A theoretical description is given and advantages to using this cell (wire ion guide cell) design are discussed. Experimental results obtained using both an elongated wire-ion guide One) cell (aspect ratio = 3.3) and a small WIG cell (aspect ratio = 1) to determine parameters affecting trapping performance are presented.
