The best solution for filament free ion beam processing on large scale!

Key Design Features

  • Filament-free source operation based on a simple, compact microwave power coupling
  • Permanent magnets for use of the Electron Cyclotron Resonance (ECR)
  • Functional ceramics for easy and quick maintenance
  • Special grid insulation and adjustment system

 

Advantages

  • Fully noble gas, and oxygen; restricted for reactive gases
  • Grid systems from different shapes and materials for optimum process adaptation
  • Minimum maintenance and long lifetime, maintenance cycles over 300 h
  • Mechanical adjustment system by universal joint (10 grd in each direction)
