Cathodic Arc Plasma System with Twist Filter: Miniaturized Cathodic Arc Plasma Source IB-1497

: André Anders, Robert MacGill and Marcela Bilek of Berkeley Lab have designed a miniaturized source to produce cathodic arc plasma that is pre-cleaned of macroparticles. The location of the plasma output is well defined, in contrast to conventional, large, DC-operated cathodic arc plasma sources. Precise plasma location is a precondition for using miniaturized macroparticle filters such as the Twist Filter described above. Miniaturization is mandatory for high plasma throughput through macroparticle filters. The researchers have demonstrated 40 A of pulsed filtered ion current using this source and the newly designed Twist Filter. These figures surpass any published or publicly known figures by a wide margin.
