SUMMARY
The primary method for measuring ion temperatures in a plasma is through the use of Langmuir probes, which are traditionally employed to assess plasma characteristics, including electron temperature. However, the discussion highlights a common misconception that Langmuir probes can directly measure ion temperatures. For accurate ion energy measurements, alternative methods may be necessary, depending on the specific plasma conditions and requirements. Researchers are encouraged to consult resources like the Review of Scientific Instruments for applicable techniques tailored to their unique situations.
