ABSTRACT:
A miniature linear ion trap (MLIT) with a length of less than 30 mm is provided for ion focusing in the axial plane. The MLIT has multipoles for applying an AC voltage to ions and tubular entrance and exit lenses for applying a DC voltage to the ions. In another aspect, MLIT includes electrodes within the tubular entrance and exit lenses for detection of image current. A method is also provided for applying voltage to the entrance and exit lenses for ion focusing.
