Workshop and Minicourse
"Kinetic Equations, Numerical Approaches and Fluid Models for Plasma Turbulence"

15-19 September 2008

Workshop Themes

Grand Physics Problems:

  • Energy cascade in gyrokinetic plasma turbulence
  • Particle heating
  • Turbulent transport
  • Gyrokinetic turbulence in sheared and rotating plasmas
Numerical and Mathematical Methods:

  • Mathematical properties of the gyrokinetic description of plasma

Information for PhD Students and Postdocs

The workshop will contain a minicourse (12 lectures), meant to be accesible to PhD students and postdocs, but open and, hopefully, interesting to everyone.

If you would like to attend please email
Alex Schekochihin (please include a short CV and a one-sentence description of your research subject; if you are a PhD student, please give the name of your adviser and the title of your PhD project; if you would like to present a poster, please give the title). There is no deadline, but the numbers we can accommodate are limited. Early expressions of interest are encouraged and will significantly increase your chances of admission.
There is no fee for this course. No financial support is available.
