A quadrupole ion trap is a type of ion trap that uses dynamic electric fields to trap charged particles. They are also called radio frequency (RF) traps or Paul traps in honor of Wolfgang Paul, who invented the device and shared the Nobel Prize in Physics in 1989 for this work. It is used as a component of a mass spectrometer or a trapped ion quantum computer.
A charged particle, such as an atomic or molecular ion, feels a force from an electric field. It is not possible to create a static configuration of electric fields that traps the charged particle in all three directions (this restriction is known as Earnshaw's theorem). It is possible, however, to create an average confining force in all three directions by use of electric fields that change in time. To do so, the confining and anti-confining directions are switched at a rate faster than it takes the particle to escape the trap. The traps are also called "radio frequency" traps because the switching rate is often at a radio frequency.
In an interview at the Institute for Quantum Computing, Dr. David Wineland of NIST (National Institute of Standards and Technology) explains the concepts and science behind ion trapping. Wineland delivered the Quantum Frontiers Distinguished Lecture (http://youtu.be/RFkyvkBV5dM) at the University of Waterloo on January 19, 2012. Wineland is a Fellow of the National Institute of Standards and Technology and group leader of the Ion Storage group in the Time and Frequency Division at NIST Boulder, CO. Find out more about IQC!

A playground ball finds stability in a saddle when the saddle is rotating at the proper speed. Mechanical analog of a "Paul Trap" particle confinement—a ball is trapped in a time-varying quadrupole gravitational potential. A large saddle shape (attached to a plywood disk) is mounted on a multi-purpose turntable. The saddle shape is essentially a quadrupole gravitational potential. Rotation of this potential subjects the ball to an alternating repulsive and attractive potential, much like the time-varying electric quadrupole potential of a Paul Trap used in trapping single ions or electrons. The plastic ball used here is about 25 cm in diameter and was purchased at a toy store. The saddle consists of a rubber sheet and fiberglass, and was hand-made with help from Justin Georgi. The turnta...
Skip to trapped particles: 1:50 This homemade "ion" trap is made up of two spoons and a loop of wire, connected to a high voltage transformer at roughly 3kV. In the video, particles of cornstarch which happen to pick up an electric charge are demonstrated being trapped. There is nothing special about cornstarch, I've also trapped baking soda, powdered sugar, dirt swept off a workbench, and a colleague volunteered his dandruff but I decided to pass on his offer. I'll leave it to someone else to post a video showing dandruff can be trapped. Despite how simple this experiment is, I haven't found any other instances online of hobbyists making ion traps, so I've decided to post this, my first ever YouTube video.

I genuinely hope that this is a solid, well-rounded, rational explanation of what might be going on. Something possible that our community can build upon and progress with. A start toward understanding what is beyond our control. My focus is on Barium, but that is only the beginning. -The cloud layer is highly reflective and refractive, creating the perfect barrier to keep out prying eyes, and to prevent certain communications. -We don’t know what is going on with the sun, and this cloud layer is perfect to cloak this. -To create ion traps by generating a cloud layer laced with Barium (possibly to deplete any unwanted gasses), send a Radio Frequency Wave through it, and harvest anti-protons for CERN’s quantum computer. How we can know that Barium is being used: -As chem-trails disperse, ...

This session was recorded during Pittcon 2013 in Philadelphia, Pennsylvania on Monday, March 18, 2013. TITLE: Converging Ion Traps for Miniaturized Mass Spectrometers AUTHOR: Daniel Austin - Brigham Young University ABSTRACT OVERVIEW: Two elements have been common to most efforts to miniaturize ion trap mass analyzers: simplification of electrode geometry and the use of either arrays or traps with extended trapping dimensions. Simplification of electrode geometry allows ion traps to be miniaturized without tolerance complications associated with machining hyperbolic surfaces. Cylindrical and rectilinear ion traps exemplify this process: each uses electrodes that are geometrically simpler than those used in the quadrupole and linear ion traps, respectively. Extended trapping dimensions, ...
