What is a tokamak?  How many tokamaks have been built?  Which is the ‘best’ tokamak in the world? Do they really promise to be an answer to the world’s energy problems? Are they dangerous?  Why haven’t they proved themselves yet?

This site does not promise to answer all these questions, as the issues are covered in the many official web-sites that you will find by following links that I provide.  It is more of a hobby for the author (who happens to work in fusion research) and a reference site for others who work in this field.  In no way does it pretend to represent the views of any other organisation (particularly of my employer) or describe fusion research to the general public. At the moment it contains information on “All-the-World’s Tokamaks” – or in other words “Tokamaks from all over the world”. Ultimately it would be nice to include “ALL the world’s Tokamaks”. Please help!   Your feedback will help me to improve the content of the site.

These pages cover ‘conventional’ tokamaks in more detail because this is currently the most mature technological approach, and the one that will be used for ITER. There is also information about ‘spherical’ tokamaks in a separate table because the important parameters are slightly different. Other promising lines of research, the ‘stellarators’ and ‘pinches’, are not included except in cases of machines which have also operated in tokamak configuration. Plasma focus devices are also not covered.

This site has been running since November 2006 and has so far had over 51,000 hits from all around the world.
