SUMTRAIC (SUMmer TRAIning Course) in plasma physics
 (Click to view larger version...)
SUMTRAIC is an experimental SUMmer TRAIning Course in plasma physics in magnetic confinement fusion devices (tokamaks) organized annually at the Institute of Plasma Physics of the Czech Academy of Sciences in Prague (IPP CAS), Czech Republic.

The centre of gravity of this summer school lays in the direct involvement of the participants in the processing and analysis of experimental data from the COMPASS tokamak or even in the participation in the experiments, when compatible with the experimental program. COMPASS is one of the leading devices among smaller tokamaks in the world, with an experimental program focused on plasma-wall interaction, edge plasma physics, H-mode and runaway electrons.

Topics in the past have included (subject to the scientific research plan of COMPASS):

  • Search for stationary zonal flows at the plasma edge using a so-called rake probe head;
  • Investigation of plasma rotation by optical diagnostic;
  • Sawtooth simulations with the code Raptor;
  • Power decay length measurements by mean of an infrared camera and divertor probes;
  • Study of the scrape-off layer turbulence, ELM detection and precursors of ELMs by mean of Lithium beam diagnostic;
  • Measurements of filamentary structures by a so called U-probe;
  • Investigation of L-mode plasma performance using neutral beam injectors;
  • SOL current measurements thanks to a five-segment floating divertor tile.
The next school will be organized in 2020. See full information here.
