Gyrokinetics in Laboratory and Astrophysical Plasmas

Por: Cambridge University
Perhaps the greatest challenge in plasma science is to understand the multiscale interaction between small-scale fluctuations and large-scale plasma dynamics. This is crucial both in fundamental astrophysical and space physics research (e.g., turbulence in the solar wind) and in more practical terrestrial contexts (e.g., the performance of the international fusion reactor, ITER, will be limited by the transport caused by small-scale fluctuations). Multiscale plasma dynamics also represent a formidable and fascinating mathematical challenge, as new analytical and numerical methods have to be developed in order for major breakthroughs to become possible.
