SUMMARY:Turbulence Driven by Compressional Magnetic Fluctuations in La
 boratory\, Space\, and Pair Plasmas\, Plasma Physics (Physics/ECE/NE 9
 22) Seminar\, Dr. M. J. Pueschel\, Institute for Fusion Studies\, Univ
 ersity of Texas at Austin
DESCRIPTION:Recent experiments conducted at the Large Plasma Device re
 veal strong compressional\, or parallel\, magnetic fluctuations in the
  region of large density and temperature gradients. Using state-of-the
 -art gyrokinetic turbulence modeling\, we show that the driver of thes
 e fluctuations is a new turbulence regime\, where plasma instability o
 ccurs due to a coupling of the ExB and grad B drifts. Implications of 
 this process include the ability of this instability to allow current 
 sheet relaxation\, thus enhancing reconnection rates in solar scenario
 s\, boosting coronal heating rates. Furthermore\, the instability is e
 ven found to occur in matter-antimatter pair plasmas in homogeneous gu
 ide fields\, a class of plasmas previously thought to be completely st
 able to pressure gradients. We discuss consequences for magnetic-confi
 nement\, laser-induced\, and astrophysical pair plasmas.  <br>
