ED2220 Experimental Fusion Plasma Physics 6.0 credits

Experimentell fusionsplasmafysik

The purpose of this course is to make the student familiar with basic experimental and diagnostic techniques used in magnetic confinement fusion plasma physics research. The student will learn about techniques for generation of high temperature toroidal fusion plasmas and be able to understand the physics underlying the common fusion plasma diagnostics methods. Experimental techniques for generation of fusion plasmas will be exemplified by studying the systems at the EXTRAP T2R reversed field pinch device at KTH. In addition, the student will gain practical experience of using some diagnostics that are available at EXTRAP T2R and analyzing real measurement data. Physics concepts underlying the plasma diagnostic methods will be introduced and discussed during lectures, using a systematic approach from first principles. A number of plasma diagnostic applications will be introduced in more detail.

After passing the course, the student should be able to

  • describe experimental techniques for generation of high temperature toroidal fusion plasmas,
  • formulate the underlying physics principles for common plasma diagnostic methods,
  • estimate measurement errors in plasma diagnostic data,
  • explain the technical features of some commonly used basic plasma diagnostic applications,
  • demonstrate the practical usage of some selected plasma diagnostics that are available at EXTRAP T2R,
  • write simple computer codes for acquiring, analyzing and plotting data from some selected plasma diagnostics using commercial software packages (IDL, MATLAB),
  • perform certain common data analysis tasks, such as Fourier transform and signal filtering using available software routines,

present analyzed data in graphic form in short reports, that includes written material that describes the diagnostic setup and the data analysis methods used.

Course main content

Experimental techniques for generation of high temperature toroidal fusion plasmas, including vacuum technology, magnets, energy storage, plasma control methods and data acquisition. Underlying principles for common plasma diagnostic methods such as magnetic measurements, measurements of plasma particle flux, measurements of plasma refractive index, electromagnetic emission by free electrons, electromagnetic emission from bound electrons, scattering of electromagnetic waves, measurements of ion processes. Practical usage of some basic plasma diagnostic applications. The selection of diagnostic applications is based on the systems available at EXTRAP T2R, and includes magnetic diagnostics, interferometer, Thomson scattering, spectrometers, bolometers, SXR camera, and electric probes.
