Field Lines in TOKAMAK: Pictures & How to Understand

Click For Summary
SUMMARY

The discussion focuses on understanding field lines in a TOKAMAK reactor, emphasizing their dynamic nature as plasma is heated and current is introduced. Participants shared resources, including a link to the Oak Ridge National Laboratory (ORNL) gallery, which provides visual representations of field lines. The conversation highlights the complexities of magnetic confinement and the instabilities that arise within the plasma, as detailed in the book "Principles of Fusion Power." This knowledge is crucial for anyone studying fusion technology.

PREREQUISITES
  • Understanding of plasma physics
  • Familiarity with magnetic confinement techniques
  • Knowledge of fusion reactor design
  • Basic research skills for accessing scientific literature
NEXT STEPS
  • Explore the ORNL gallery on TOKAMAK field lines
  • Read "Principles of Fusion Power" for in-depth knowledge
  • Investigate the effects of plasma heating on magnetic confinement

How look field lines in TOKAMAK? Do you have any picture? How I could physically make for a better understanding? (of paper, laser, ...)

Did you try to do a search on this? I did a google search on your phrase "field lines in TOKAMAK" and got a slew of hits, including one at ORNL

http://www.ornl.gov/sci/fed/mhd/tokamak_gallery.html

Were you having problems finding such things?

I searched for it on the Czech internet and I didn't found some suitable. When I searching in English, I'm not too sure if I found the correct content.
Thank you.
 
Keep in mind that the field lines change drastically inside the reactor when you heat the plasma up and introduce current through it. I've got a book on Principles of Fusion Power and there are numerous issues with the field lines getting all mucked up inside the plasma, leading to instabilities and such. It's one of the main challenges with magnetic confinement methods.
