The unique solution for filament free ion beam processing


RF/F 40 and RF/I 40

Key Design Features

  • Filamentfree source operation based on a simple, rugged inductive power coupling
  • Compact impedance matching inside the source housing
  • Internal and external mounting configurations
  • Functional ceramics for easy and quick maintenance
  • Special grid insulation and adjustment system



  • Fully noble gas, oxygen, and other reactive gas capability
  • Grid systems from different shape and material for optimum process adaptation
  • RF power supply via 50 W cable without additional matching unit
  • Minimum maintenance and long lifetime
