Electron-capture, ionization, and recoil-ion-production cross-sections are measured and calculated for fast highly charged projectiles in hydrogen and rare-gas targets. Recoil-ion-production cross-sections are found to be large; the low energy and hi

Atomic inner-shell processes involving excitation, ionization, and charge transfer have been investigated for MeV/amu Ar+Xe collisions. The individual processes were isolated and identified by detecting coincidences between argon K x rays and the out

We report cross-section measurements for collisions of multicharged iron ions with a molecular-hydrogen target: (a) electron capture and electron loss of the multicharged ions, and (b) impact ionization of the hydrogen target. Iron ions, Fe/sup +q/,

In this paper, we have determined the net ionization cross section for total slow-ion or slow-electron charge production in rare-gas targets by passage of a fast projectile both experimentally and theoretically. We have experimentally studied ionizat

Cross sections for single-electron capture and for impact ionisation of Feq+ (q=10,15,20,25) ions incident on atomic hydrogen have been calculated in the energy range 50 to 1200 keV amu-1 using a classical-trajectory Monte Carlo method. Cross section

The 10×40‐cm long pulse neutral beam source developed at Lawrence Berkeley Laboratory has been selected as the prototype for the design of the U. S. common long pulse source to be used on tokamak fusion test reactor (TFTR), Doublet‐III, and mirr

Cross sections for Cs/sup 2 +/ formation in Cs/sup +/+Cs/sup +/ collisions have been measured by a plasma-target technique for center-of-mass energies from 50 to 110 keV. The measured cross sections for the sum of ionization and charge exchange are i

The U.S. magnetic fusion energy program has developed a single design long pulse neutral beam source for TFTR, MFTF-B, and DIII-D. The arc is a very compact axial magnetic line cusp. The accelerator is an actively cooled tetrode with water cooled gri
