Area of Science:

  • Plasma Physics
  • Diagnostic Techniques
  • Materials Science

Background:

  • Plasma potential (V(p)) is crucial for determining electrostatic fields in plasmas.
  • Emissive probes approximate V(p) under space-charge limited emission.
  • Tungsten filaments limit traditional probes in high-density plasmas (>10(12) cm(-3)).

Purpose of the Study:

  • Develop a robust emissive probe for high-density plasma diagnostics.
  • Evaluate the performance of a cerium hexaboride (CeB6) emitter probe.
  • Compare measurements with existing diagnostic methods.

Main Methods:

  • Constructed a resistively heated emissive probe utilizing a CeB6 emitter.
  • Operated the probe in plasma densities up to 10(13) cm(-3).
  • Compared V(p) profiles obtained from the CeB6 emissive probe, a cold floating probe, and a swept probe in current-carrying and non-current-carrying plasma regions.

Main Results:

  • The CeB6 emissive probe demonstrated functionality in high-density plasmas.
  • Measurements from the CeB6 emissive probe and the swept probe showed good agreement.
  • The cold floating probe provided inaccurate readings in the current-carrying plasma region.

Conclusions:

  • CeB6 emitters are suitable for emissive probes in high-density plasma environments.
  • The developed emissive probe offers a reliable method for measuring plasma potential.
  • This advancement improves plasma diagnostic capabilities in challenging conditions.
