Transport of energetic electrons in a magnetically expanding helicon double layer plasma

Peripheral magnetic field lines extending from the plasma source into the diffusion chamber are found to separate two regions of Maxwellian electron energy probability functions: the central, ion-beam containing region with an electron temperature of 5 eV, and region near the chamber walls with electrons at 3 eV. Along the peripheral field lines a bi-Maxwellian population with a hot tail at 9 eV is shown to both originate from electrons in the source traveling downstream across the doublelayer and correspond to a local maximum in ion and electron densities.http://link.aip.org/link/APPLAB/v94/i19/p191503/s1
