Autor: C.C. Tsai, H. H. Haselton, S. M. Gorbatkin, James B. Roberto, W. L. Stirling, Lee A. Berry
Publikováno v: Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films. 8:2900-2903
An electron cyclotron resonance (ECR) multicusp plasmatron has been developed by feeding a multicusp bucket arc chamber with a compact ECR plasma source. This novel source produces large (about 25 cm diam), uniform (to within ±10%), dense (>1011 cm

Publikováno v: Review of Scientific Instruments. 61:783-787
The emittances of hydrogen and deuterium negative ion beams produced by volume ion sources have been measured in a transverse plane normal to the beam trajectory. The extraction voltage was varied from 10 to 40 kV, and the transverse magnetic field i

A neutral particle beam system for ITER with RF acceleration
Autor: W. L. Stirling, H. H. Haselton, J.H. Whealton, W. R. Becraft
Publikováno v: IEEE Thirteenth Symposium on Fusion Engineering.
A concept for a current drive system that is based on negative ions with beam energies >1 MeV is presented. Preliminary physics calculations, which are discussed, show that the core current necessary for stability enhancement can be achieved by beams

Publikováno v: IEEE Transactions on Nuclear Science. 26:1281-1286
Ion beam technology has advanced immensely during the past 15 years in connection with the application of neutral beam injection heating for fusion research. Ion sources have been scaled up along with necessary modifications, yielding currently a few

Publikováno v: Physical Review A. 10:745-748
The foil-excitation method has been used to study the extreme ultraviolet spectra of highly ionized oxygen and fluorine. Several previously unreported lines in heliumlike fluorine are reported and other newly reported lines in heliumlike oxygen have

Experimental comparison is made of four plasma grids, each with a specific aperture geometry, in an attempt to improve the ion optics of a multiple aperture ion source. It is clearly shown that a simple notch geometry outperforms the other candidates
