Illustration of a Penning trap, a device that uses electric and magnetic fields to trap charged particles (ions). The two batteries at the two ends produce the electric field (red field lines). The magnetic field lines (green) travel from bottom to top.

In a Penning trap charged particels (ions) can be stored with a superposition of a magnetic field and a static electric field. The magnetic field prevent the charged particel to escape perpendicular to the magnetic field lines (The ion travels on a cyclotron-like orbit).

One of the Antimatter group's chief projects in the past decade has been the design, fabrication, and testing of a portable antiproton trap (Penning trap) named "Mark I", which can store 1010 antiprotons for one week.

We report a study of the axialization and laser cooling of single ions and small clouds of ions in a Penning trap. A weak radiofrequency (rf) signal applied to a segmented ring electrode couples the magnetron motion to the cyclotron motion, which results in improved laser cooling of the magnetron motion.

The Canadian Penning Trap Mass Spectrometer (CPTMS) is currently situated at Argonne National Laboratory, Illinois, USA. This system was originally conceived for the precision mass measurement of "exotic" (radioactive) nuclei with half-lives greater than 50ms to a precision of 1 part per billion (ppb) of the mass.
