Ion optics components and method of making the same

An ion optics component comprising:

• a first electrode sub-assembly comprising an electrically isolating material supporting a first plurality of electrode bodies defining at least two poles of a multipole ion guide structure, the first plurality of electrode bodies formed on, integrated with and in a predetermined alignment one relative to the other on the electrically isolating material of the first electrode sub-assembly;
• a second electrode sub-assembly comprising an electrically isolating material supporting a second plurality of electrode bodies defining at least two other poles of the multipole ion guide structure, the second plurality of electrode bodies formed on, integrated with and in a predetermined alignment one relative to the other on the electrically isolating material of the second electrode sub-assembly;
• and
• a mounting structure fixedly secured to the first electrode sub-assembly and to the second electrode sub-assembly, the mounting structure supporting the first plurality of electrode bodies in a predetermined alignment relative to the second plurality of electrode bodies;
• at least two of the first plurality of electrode bodies having surfaces facing towards a centerline of the ion optics component that are other than parallel to first and second major surfaces of the first electrode sub-assembly, and at least two of the second plurality of electrode bodies having surfaces facing towards the centerline of the ion optics component that are other than parallel to first and second major surfaces of the second electrode sub-assembly.
