PFC / JA - 92 - 16 Bootstrap Current Induced by Fusion Born Alpha Particles
نویسندگان
چکیده
The bootstrap current produced by fusion born alpha particles is obtained retaining effects of slowing down drag, pitch angle scattering, and arbitrary aspect ratio. The result is presented both as a summation of a rapidly converging series and a simple Pade approximation good for arbitrary aspect ratio. Quantitative results are derived using International Thermonuclear Experimental Reactor (ITER)' parameters.

On the approximations of the distribution function of fusion alpha particles
The solution of the drift-kinetic equation for fusion-born alpha particles is derived in the limit of dominant parallel streaming, and it is related to the usual slowing-down distribution function. The typical approximations of the fast tail of fusion-born alpha particles are briefly compared and discussed. In particular, approximating the distribution function of fast-alpha particles with an “...

A large-angle, 60 GHz collective Thomson scattering (CTS) diagnostic system for localized measurements of DT alpha-particle velocity distribution and fraction is being implemented on TFTR. Calculations of expected CTS spectra, signal to noise ratio per receiver channel, and estimated error in determining the temperature and fraction of alpha-particles are being carried out. The experimental spe...

متن کاملFirst gamma-ray measurements of fusion alpha particles in JET trace tritium experiments.
Gamma-ray spectra from nuclear reactions between fusion-born alpha (alpha) particles and Be impurities were measured for the first time in deuterium-tritium plasmas in the Joint European Torus. The time dependence of the measured spectra allowed the determination of the density evolution of fast alpha particles. Correlation between the decay time of the gamma-ray emission and the plasma paramet...
متن کاملMicroturbulence driven transport of energetic ions in the ITER steady-state scenario
Modelling of microturbulence-driven transport of energetic ions in an ITER steady-state scenario is presented. Results indicate that a significant fraction of the velocity space distribution of alpha particles and deuterium ions can be transported above neoclassical predictions. Turbulent magnetic fluctuations are found to significantly enhance the fast ion diffusivity. Overall, the conclusion ...
