The Theory of the Electromagnetic Field
Consider a linear quadrupole consisting of a point charge of strength 2q at the
origin and point charges of strength —q at (0, 0, a) and (0, 0, —a). Show that the
monopole and dipole moments of this distribution are zero, calculate the
elements ...

Mass Spectrometry Basics
To give ions this forward momentum, they are often accelerated through a
potential of about 5 V, maintained between the ion source and the quadrupole.
Sometimes sufficient momentum arises naturally from space-charge effects from
...

The far-field pressure of a longitudinal quadrupole has directivity cos2 & and
decays inversely with distance from the source. In the near field the pressure
varies with the inverse cube of distance from the source and has directivity I - 3
cos2 8.

Handbook of Charged Particle Optics, Second Edition
The x-directional beam has a focus at the second quadrupole. The beam has an
elongated shape in the y-direction at this plane. The second quadrupole lens has
a focusing action in the x-direction and forms a focus at the third quadrupole.
