The energy spread of some negative ions from a sputter source
نویسندگان
چکیده
2014 Energy distribution measurements on 20 keV beams of 12C-, 32S-, 127I-, Hand 160have shown no obvious differences between Hand 16Oon the one hand, which are believed to be produced in an adsorbed layer on the target, and 12C-, 32Sand 127Ion the other which are part of the target material. All spectra have a single peak and a FWHM of the order of 10-12 eV. The significance of the energy distribution in the calculation of beam brightness is also discussed.

A pulsed sputter negative ion source
2014 A pulsed source for Cs-ions has been constructed as part of a sputter ion source in Hortig geometry. A beam of Cs-ions is extracted from a tungsten surface ionizer and bunched into pulses a few ns wide by a combination of velocity and path-of-flight modulation. It is expected that such a beam will produce intense pulses of negative ions having pulse widths in the ns range. REVUE DE PHYSIQU...
متن کاملStudy on the Ionic Bombardment in a Glow Discharge Lamp
The surface of copper alloys was studied by means of a scanning electron microscope after having been sputtered by a glow discharge source under typical conditions for spectrochemical analysis. The surface topography developed during the process of sputtering gave the following two results: It would appear that the energy spread of the bombarding ions is small and the variation in the angles of...
متن کاملConceptual Design of a Sputter-type Negative Ion Source Based on Electron Cyclotron Resonance Plasma Heating
A design for a negative ion source based on electron cyclotron resonance plasma heating and ionization by surface sputtering is presented. The plasma chamber of the source is an rf-cavity designed for TE111 eigenmode at 2.45 GHz. The desired mode is excited with a loop antenna. The ionization process takes place on a cesiated surface of a biased converter electrode (cathode). The ion beam is fu...
متن کاملA Study of the Tribological Properties of Sputter-deposited MoSX/Cr Coatings
In this investigation, MoSx/Cr coatings were deposited by direct-current magnetron sputter onto Ck45 (AISI 1045) plain carbon steel substrates. The MoSx/Cr ratio in the coatings was controlled by sputtering the composite targets. The chemical characterization was performed using EDX (energy dispersive X-ray analysis); the structural characterization was accomplished by X-ray diffraction (XRD) s...
متن کاملAn attempt to detect stable N- ions from a sputter ion source and some implications of the results for the design of tandems for ultra-sensitive carbon analysis
2014 The present paper discusses an experiment, using a Middleton sputter ion source, where a sensitive search was made for 14Nions in the presence of an intense carbon beam. It was found that negative nitrogen ions, capable of withstanding acceleration fields of 1.5 MV/m, were not produced in detectable intensities. The paper also points out some design requirements of tandem facilities that m...
