Langmuir Probes

Langmuir probes are diagnostic tools used in plasma research to measure the properties of plasma, a state of matter made up of charged particles. These probes consist of a small electrode inserted into the plasma, which collects electrons and ions. By analyzing the resulting electrical current based on varying voltage applied to the probe, researchers can determine key plasma characteristics, such as electron temperature, density, and potential. This information is crucial for understanding plasma behavior in applications like fusion energy, space weather, and industrial processes.
