Self‐emissive probes

A high‐density magnetized plasma is seen to heat small diameter tungsten wire probes to electron emission. The use of these self‐emissive probes to determine the plasma potential in a tandem mirror plasma is investigated. A simplified model is presented and comparison is made with conventional emissive probe behavior.
