Abstract

Ion clouds of different species and variable size are stored in a 3D Paul trap and detected after extraction from the trap. We report on measurements of the superimposed stability regions of four simultaneously stored ion species. We determine the operating conditions for trapping capacity under variation of buffer gas pressure and observe space charge shifts for a specific ion in the presence of other elements.
