Traps: Historical Overview & Design of Common Traps

It has been over half-a-century since electromagnetic traps were first demonstrated. Since then they have found their place at the heart of time-keeping equipment, mass spectrometers, and experimental quantum processing devices.

We discuss below some of the most common trap designs.

The Penning Trap
The Penning Trap The Penning trap uses a combination of static electric and magnetic fields to achieve 3-D confinement of charged particles.

The Paul Trap
The Paul Trap First demonstrated around 1960, the Paul trap uses a combination of an electrostatic (DC) field combined with a variable radio-frequency (RF) electrical field to achieve 3-D confinement of charged particles.

Dr. Wolfgang Paul
Dr. Wolfgang Paul Wolfgang Paul (1913-1993) was a German physicist, who invited the RF quadrupole ion trap.

A Cylindrical Ion Trap
A Cylindrical Ion Trap Due to manufacturing constraints and other practical considerations, one most often uses traps that have shapes that deviate considerably from the ideal hyperbolic geometry. The cylindrical geometry is a substitute…
