    • An overview is given of the experimental method, the analysis technique and the results for trace tritium experiments conducted on the JET tokamak in 2003. Observations associated with events such as sawtooth collapses, neo-classical tearing modes and edge localized modes are described. Tritium transport is seen to approach neo-classical levels in the plasma core at high density and low q(95), and in the transport barrier region of internal transport barrier (ITB) discharges. Tritium transport remains well above neo-classical levels in all other cases. The correlation of the measured tritium diffusion coefficient and convection velocity for normalized minor radii r/a = [0.65, 0.80] with the controllable parameters q95 and plasma density are found to be consistent for all operational regimes (ELMy H-mode discharges with or without ion cyclotron frequency resonance heating, hybrid scenario and ITB discharges). Scaling with local physics parameters is best described by gyro-Bohm scaling with an additional inverse beta dependence.

  • Thermodynamic modeling of the Nb-Si system
  • 2002
  • Ingår i: Intermetallics (Barking). - 0966-9795 .- 1879-0216. ; 10:10, s. 993-999

    • Optimized coefficients of the Gibbs free energy expression for each stable phase of the binary Nb-Si have been obtained, using the Thermo-Calc program for this purpose. The Nb3Si, alphaNb(5)Si(3), NbSi2 and Diamond (Si) have been modeled as stoichiometric phases and the liquid L, BCC (Nb) and the betaNb(5)Si(3) phases as solutions, with the excess term described using the Redlich-Kister formalism. The Si solubility in the betaNb(5)Si(3) phase has been modeled according to two possibilities: (i) Si substituting for Nb and (ii) vacancies in the Nb positions. The calculated diagrams compare well with the experimental information taken from the literature.
