Retarding Potential Analyzer (RPA / RFEA)

Measures ion energy distribution and flux for surface processing, ion beam etch, and thruster plume spectrum analysis.

Retarding Potential Analyzer (XHINS-RPA)

High-resolution ion energy and flux diagnostics

XHINS-RPA uses a tunable retarding grid and energy-selective collector to measure IEDFIEDF and ion flux, supporting step/linear scans and low-noise front-ends. Suited for low/high flux, thruster beams, and process energy spectrum evaluation.

Key Features

  • Measures ion energy distribution (IEDFIEDF) and ion flux
  • Tunable retarding grid with step/linear scan modes
  • Low-noise front-end covering pA to mA ranges
  • Cooling/high-power options; easy to pair with scanning or arrays
