The Snowflake Divertor

The snowflake is not usually associated with extremely high temperatures – yet this image is from the hottest part of a tokamak, the divertor. The snowflake divertor is a new approach to managing the intense heat loads generated by fusion experiments, based on a complex magnetic field configuration. The success of this approach earned a prestigious “R & D 100″ award for the team that developed it, from the EFDA’s Swiss Associate CRPP, and the Lawrence Livermore National Laboratory, US and Princeton University, US.
