SUMMARY:Exploring turbulence saturation in 3D plasmas\, Plasma Physics
  (Physics/ECE/NE 922) Seminar\, Dr. Benjamin Faber\, Department of Eng
 ineering Physics\, University of Wisconsin-Madison
DESCRIPTION:Minimizing energy and particle losses due to microturbulen
 ce remains a significant challenge facing magnetic confinement fusion 
 energy.  In this talk\, I will examine the physics of turbulence satur
 ation in three-dimensional stellarator plasmas\, highlighting recent t
 heoretical and computational achievements. In particular\, I will focu
 s on turbulent saturation induced by nonlinear three-wave energy trans
 fer between stable modes at the same scales as the driving instability
 \, and show the three-wave coupling mechanism is dependent on local ge
 ometry.  These insights into geometric dependence of saturation provid
 es valuable input for future stellarator optimization schemes focused 
 on reducing turbulent transport.
