quadrupole

A system of four electric charges or magnetic poles arranged in a specific configuration to create a non-uniform field. / A type of antenna consisting of two poles oriented in opposite directions, typically used for VHF communications. / In nuclear physics, a measure of the non-spherical distribution of charge or mass within an atomic nucleus.
Noun
pl: quadrupoles

This term is used exclusively within technical and scientific registers, specifically in physics, electromagnetism, and radio engineering. It describes a specific geometric arrangement of four poles or charges, distinguishing it from simpler configurations like dipoles (two poles) or more complex ones like octupoles (eight poles).

In a practical laboratory or industrial context, the word often refers to the physical hardware, such as a quadrupole mass spectrometer or a focusing magnet. In theoretical nuclear physics, it refers to a mathematical property (the quadrupole moment) that describes the shape of a nucleus, where a non-zero value indicates a deviation from a perfect sphere.
