<\/a>Langmuir Probe:<\/b> This device measures current in plasma, it is basically a third electrode stuck into a gas discharge tube. The difference between the current detected in the Langmuir Probe and the plasma space potential can tell you the ion and electron densities of the plasma. More ><\/a><\/p>\n

While the Langmuir Probe is not an “ammeter” it is an example of how Unit I of this series (Ammeters, Voltmeters) form the foundation for other rather spectacular and complex instruments.<\/p>\n\n\n\n
