Langmuir Probe Theory

A Langmuir probe is a device used to measure properties of plasma, which is an ionized gas found in environments like stars and fusion reactors. It consists of a thin electrode inserted into the plasma. By applying a voltage to the electrode and measuring the current that flows, scientists can determine the density, temperature, and energy of the charged particles in the plasma. This information helps researchers understand the behavior of plasmas in various applications, from space science to industrial processes. Essentially, the Langmuir probe acts like a sensor for analyzing the characteristics of ionized gases.
