Langmuir Probes

Langmuir Probe


Langmuir Probe

The Langmuir Probe is one of the most common and widely used plasma diagnostics and measures parameters in the bulk of the plasma.

Plasma Parameters Measured:
Floating Potential • Plasma Potential • Plasma Density • Ion Current Density • Electron Energy Distribution Function • Electron Temperature

Langmuir Spatial Probe

Langmuir Spatial Probe

The Langmuir Spatial Probe uses an automated linear drive to scan across a plasma and take measurements of plasma parameters at different locations.

Plasma Parameters Measured:
Floating Potential Uniformity • Plasma Potential Uniformity • Plasma Density Uniformity • Ion Current Density Uniformity • Electron Energy Distribution Function
