Abstract

A radio-frequency quadrupole which includes four, extruded, identical cross-section, elongate structural components, each of which lacks any longitudinally extending plane of bilateral assembly. Joinder of these components to form a quadrupole body results in an overall axial cross-sectional configuration which has an infinite number of claims of inverted bilateral symmetry extending in all radial directions relative to the long axis of that body. Coolant-carrying boreholes extend longitudinally throughout each component with precise location and proper longitudinal-axial-parallelism.
