    Notes: Abstract The carbon plasma ion energies produced by the pulsed filtered arc-discharge method have been measured as a function of the anode-cathode voltage. The energies were determined by using the electro-optical time-of-flight method. The highest anode-cathode voltage was 5 kV and yielded the energy of 140 eV for the plasma ions. In addition, it was demonstrated that a rather slight change of the parameters in the arc-discharge method has a strong effect on the plasma ion energies and the properties of the diamond-like coatings prepared.

    Radiation enhanced outdiffusion during ion implantation (1979)
    Springer
    Applied physics 19 (1979), S. 199-203

    ISSN: 1432-0630

    Notes: Abstract For a systematic prediction of the radiation-enhanced outdiffusion occurring during implantation, the use of a model based on the effect of vacancy flow on diffusion is described. The model agrees reasonably well with experiments in all twentysix measured cases. For the systematic understanding of the radiation enhanced outdiffusion, an approximative diagram based on the activation energy of self-diffusion is constructed for all pure elements and its application possibilities are discussed.

    Long-duration high-energy proton events observed by GOES in October 1989 (1998)
    Springer
    Annales geophysicae 16 (1998), S. 921-930

    Notes: Abstract We consider the prolonged injection of the high-energy (〉 10 MeV) protons during the three successive events observed by GOES in October 1989. We apply a solar-rotation-stereoscopy approach to study the injection of the accelerated particles from the CME-driven interplanetary shock waves in order to find out how the effectiveness of the particle acceleration and/or escape depends on the angular distance from the shock axis. We use an empirical model for the proton injection at the shock and a standard model of the interplanetary transport. The model can reproduce rather well the observed intensity-time profiles of the October 1989 events. The deduced proton injection rate is highest at the nose of the shock; the injection spectrum is always harder near the Sun. The results seem to be consistent with the scheme that the CME-driven interplanetary shock waves accelerate a seed particle population of coronal origin.
