Penning Trap
Penning traps are devices for the storage of charged particles using a homogeneous static magnetic field and a spatially inhomogeneous static electric field. This kind of trap is particularly well suited to precision measurements of properties of ions and stable subatomic particles which have a non-zero electric charge. Recently this trap has been used in the physical realization of quantum computation and quantum information processing as well. The Penning trap has also been used in the realization of what is known as a geonium atom. Currently Penning traps are used in many laboratories worldwide. For example, they are used at CERN to store antiprotons.

Famous quotes containing the word trap:
“And boys, be in nothing so moderate as in love of man, a clever
servant, insufferable master.
There is the trap that catches noblest spirits, that
caught—they say—God, when he walked on earth.”
—Robinson Jeffers (1887–1962)
