Executive summary: Co-Inventor of the ion trap

German physicist Wolfgang Paul invented the Paul trap, a device that made possible the detailed study of subatomic particles by trapping individual ions for extended observation. A Paul trap is similar to Hans G. Dehmelt's Penning trap, but is based on somewhat different principles. It features two electrical plates or end caps, with a circular electrode between, which traps particles in its electrical field, but isolates these trapped ions and electrons from temperature, pressure, and other outside influences. The device's trapping mechanism made possible the development of atomic clocks, and has proven valuable in the study of atomic structures. With Dehmelt and Norman F. Ramsey, Paul won the Nobel Prize in 1989.

Not to be confused with Wolfgang Pauli, an earlier Nobel laureate in Physics.
