ABSTRACT:
A method for manufacturing a multipole assembly for use in mass spectrometers, residual gas analyzers, mass filters, ion containment apparatus and particle beam accelerators. A precision mandrel tool is utilized for positioning a plurality of electrode rods in position during the manufacturing process. The electrode rods are placed on the mandrel. At least one insulator is positioned about the mandrel-rod assembly such that the mandrel-rod assembly psses through the insulator. The rods are tightly clamped to the mandrel and adhesive is placed in a gap established between each rod and the insulator. The adhesive is cured such that it acts both as a rigid bond between the insulator and each rod, as well as a precision spacer for positioning each rod in a precision position after the mandrel is removed from the assembly.
