Note: Arc discharge plasma source with plane segmented LaB6 cathode

Rev Sci Instrum. 2016 May;87(5):056106. doi: 10.1063/1.4950903.

Abstract

A plane cathode composed of close-packed hexagonal LaB6 (lanthanum hexaboride) segments is described. The 6 cm diameter circular cathode is heated by radiation from a graphite foil flat spiral. The cathode along with a hollow copper anode is used for the arc discharge plasma production in a newly developed linear plasma device. A separately powered coil located around the anode is used to change the magnetic field strength and geometry in the anode region. Different discharge regimes were realized using this coil.
