Solving a longstanding mystery, MIT experiments reveal two forms of turbulence interacting.

Summary:

A new computer model finds that electrons are more important in plasma interactions than previously believed. A simulation of more than 10 million computer hours has demonstrated that electrons are as important as ions for instablity and turbulence problems. The results of this simulation have been simplified into a new computer algorithm that can complete on an ordinary household computer in a reasonable period of time.

Turbulence is a long-standing problem that leads to heat losses in the plasma.

A long-standing discrepancy between predictions and observed results in test reactors has been called “the great unsolved problem” in understanding the turbulence that leads to a loss of heat in fusion reactors. Solving this discrepancy is critical for predicting the performance of new fusion reactors such as the huge international collaborative project called ITER, under construction in France.
