Cathodic Arc Plasma System with Twist Filter – Triggerless Method of Cathodic Arc Initiation IB-1489

Ernest Orlando Lawrence Berkeley National Laboratory

APPLICATIONS OF TECHNOLOGY:

  • Vacuum arc ion sources
  • Mevva ion sources

ADVANTAGES:

  • Simple method
  • Can be used with large number of cathode materials
  • Cathodic arc can be initiated without the need for a high-voltage trigger pulse

ABSTRACT

André Anders has developed a simple method by which a cathodic arc can be initiated without the need for a high-voltage trigger pulse. “Triggerless” initiation can also be used in vacuum arc ion sources, also known as Mevva ion sources. Berkeley Lab’s new “triggerless” principle has been used successfully with a large number of cathode materials.
