- n. Anything having six poles or electrodes
Sorry, no etymologies found.
Göttingen in the late forties I had attended a seminar given by Helmut Friedburg, a doctoral Student of Wolfgang Paul, on focussing spins with a magnetic hexapole.
In this case the excited hydrogen atoms are selected by a hexapole magnet (Paul).
A common magnet has two poles and is called a dipole, one with four poles, a quadrupole, one with six, a hexapole etc.
Paul has shown that a magnetic hexapole, used for instance in a hydrogen maser, focuses beams of atoms having a magnetic dipole moment.
They also injected the RF radially into the source using an open-versus a closed-hexapole structure.
