Notes:
A washer plasma gun for alkali-metal plasma is developed. This gun is suitable as a source for experiments on alkali-metal plasmas, plasma diagnostics, and in various applications such as ion-beam sputter deposition. The gun uses an injector of alkali-metal vapor based on the principles of laser ablation. Acceleration is performed by a large electrical field provided across eight washers. The gun is compact, stable, and easy to fabricate and use. The gun produces a neutral Li0 beam current of 1 A/cm2 and a Li+ ion current of 50 A/cm2 at its exit at 10 kV of capacitor bank voltage. With this intensity, it is possible to produce beams of neutral Li0 atoms of density 6×109 cm−3 and Li+ ions of density ∼1011 cm−3 at 1 m from the gun, moving with a velocity of ∼107 cm/s.
