Abstract
A new type of plasma source is presented: A collisionless plasma is formed by producing ions on one end and electrons on the other of a cylindrical vacuum chamber in a solenoidal magnetic field. The ions are produced by contact ionization of potassium on tungsten. The source of electrons is a LaB6 plate. In the usual single-ended Q machine the elements rhenium, iridium, and platinum are tested as ionizing metals for potassium and barium.This publication has 9 references indexed in Scilit:
