Abstract
It is proposed to improve transmission of ions along the curved path of an ion guide by changing the separation between adjacent multipole rods in the plane of curvature. As the separation increases along the length of the device, the ion confinement in the plane of curvature decreases. At the same time, the external field penetration from the electrodes outside of the main ion guide increases which can be used to create additional DC field gradients to facilitate ion confinement and motion through the ion guide.
