abstract
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 (WIG) cell (aspect ratio = 3.3) and a small WIG cell (aspect ratio = 1) to determine parameters affecting trapping performance are presented. 1995, Elsevier Science B.V.
