Faraday Probe
Our Faraday probes directly measure ion beam or plasma beam current density and spatial distribution. Typical forms include single and dual Faraday probes for quantifying thruster plumes, plasma sources, and process beams.
Single Faraday Probe
Simple structure, easy calibration for single-point beam and total current measurement
The XHINS-FP system is built for diagnosing plasma and ion beam characteristics. It measures ion current distribution to evaluate beam uniformity in etch tools, propellant utilization and energy loss in EP systems, plume divergence, and thrust vector alignment. The compact Faraday probe is easy to calibrate for point current and current density. Mounted on linear/rotary stages, it enables spatial scanning and beam profiling to locate non-uniformity and divergence sources. Suppression grids reduce secondary electron effects for higher accuracy.

Faraday Probe Array
Multi-channel synchronous capture for transient spatial profiles
Arrays combine multiple collectors for simultaneous channels, capturing transient spatial distributions and fast-changing beam structures. Linear or planar layouts with high-speed electronics deliver time-resolved profiles for pulsed or noisy environments.
Key Features
- Synchronous multi-channel sampling for transient spatial profiles
- Array layouts for high-resolution profiling and differential analysis
- Scalable channel count and dynamic range for strong/weak beams
- Pairs with high-speed electronics for pulsed/transient analysis
