Probe Bundles
Plasma Plume Analysis Kit
Core value: accurately assess thruster health and plume characteristics—an entry kit for performance testing and optimization.
Typical use: ground-vacuum performance tests and plume characterization of ion thrusters or Hall thrusters.
Includes: one Faraday probe set + one RPA set.
Pain point solved: Faraday alone gives current; RPA alone gives energy. Together they deliver a full plume profile—“how strong and how well-directed.”
- Ion current density spatial distribution (Faraday): plume angular profile, thrust vector direction, beam focusing.
- Ion energy per charge distribution (RPA): effective acceleration voltage, energy utilization, low-energy tail detection.
Comprehensive Plasma Diagnostics Platform
Core value: deep insight into plasma generation, acceleration, and interactions—ideal for mechanism studies and advanced performance analysis.
Typical use: novel EP R&D, spacecraft–plume interaction, contamination assessment.
Includes: Langmuir probe + Faraday probe + RPA.
Pain point solved: adds Langmuir to diagnose background plasma and potential distribution, covering charging/erosion risks beyond plume strength and energy.
- All parameters from Bundle A.
- Background electron temperature and density (Langmuir): neutrality level, surface potential prediction.
- Plasma potential spatial distribution (Langmuir): electric field profile, ion acceleration, electron transport.
Particle Energy Analysis Kit
Core value: focuses on energy dimension for detailed diagnostics of energetic electrons and ions.
Typical use: Hall thruster non-ideal effects, high-energy particle studies, cases needing precise energy distribution functions.
Includes: RPA + EB probe.
Pain point solved: RPA targets ion spectra; EB (electron energy analyzer) yields electron energy distribution to reveal transport and loss mechanisms.
- Ion energy distribution function (RPA).
- Electron energy distribution function (EB): refined electron temperature and high-energy tail identification.
