The Paul trap, which he developed in the 1950s, used a radio-frequency
current to maintain an alternating electric field that isolates and
confines charged particles and atoms in a small space. The Paul trap
allowed physicists to study atomic properties and test physical theories
with high degrees of precision and became an important tool in modern
spectroscopy. Paul also invented a way of separating ions of different
masses and storing them in the Paul trap, using a principle that was
subsequently widely applied in modern spectrometers.
