Ion Trap

An ion trap is a device used in physics and chemistry to hold charged particles, called ions, in a specific location using electric and magnetic fields. Think of it like a three-dimensional “cage” made of electric fields that confine ions in space without physically touching them. This allows scientists to study, manipulate, or analyze the ions with precision. Ion traps are essential in applications such as mass spectrometry for identifying molecules, quantum computing research, and fundamental physics experiments, providing a controlled environment to work with charged particles over extended periods.
