A quadrupole or quadrapole is one of a sequence of configurations of things like electric charge or current, magnetic fields, or gravitational mass that can exist in ideal form, but it is usually just …

…of focusing magnet is a quadrupole, a magnet built with four poles (two norths and two souths) arranged opposite each other. This arrangement pushes particles toward the centre in one …

The quadrupole moment is a measure of the deviation of an object's charge distribution from spherical symmetry. It is a higher-order multipole moment that describes the degree to which …

The meaning of QUADRUPOLE is a system composed of two dipoles of equal but oppositely directed moment.

Jan 2, 2025 · While calculations of the quadrupole moment for a given nuclei are beyond the scope of this page, the moments for the nuclei have been calculated and a few examples are …

Understand the concept of an electric quadrupole, its field distribution, and the mathematical representation of this phenomenon in physics.

Some of the confusion over factors of two, and "primitive" versus "traceless" comes from this use of the quadrupole moment as a coefficient in different expansions describing different properties.

A typical high-performance quadrupole will have rods of 1 cm diameter and 25 cm in length, possibly preceded by an ac-only quadrupole prefilter. The ac voltage will be in the megahertz …

Jun 9, 2023 · What are Quadrupole Fields? Quadrupole fields, on the other hand, are a bit more complex. They have two north poles and two south poles, creating a kind of four-pole setup. …
