Abstract : This application discloses an atomic source for obtaining atomic species from their parent molecules by dissociation thereof. Energy of dissociation is applied from a microwave source using a coupling tube in a vacuum chamber. Extension of the discharge tube to the tip of the source permits discharge to occur adjacent to an orifice at the end of the discharge tube. A stationary O-ring vacuum seal at the tip of the discharge tube allows cooling gas to be circulated along the surface of the tube, beginning with the discharge region, and out through a central annulus at the opposite end of the source. The microwave cavity is approximately 1-1/4 wavelengths in length, with energy coupled into the cavity 1/4 wavelength from the end of the cavity opposite the discharge end.
