A new plasma source, the "plasma emitter," was successfully developed by using thermionic plasma emission from a mixture of aluminosilicate and barium oxide. At an operating temperature around 1300 K, we have a plasma of density 1×107-2×108 cm-3 and temperature ≃0.16 eV. The plasma emitter, being quite simple in its construction and especially cheap, is very useful for various kinds of plasma experiments and applications.
