SUMMARY:Kinetic Simulations of Plasma Turbulence Using the Discontinuous G
 alerkin Finite Element Method
DESCRIPTION:Tess Bernard (University of Texas), Ammar Hakim and Gregory Ha
 mmett (Princeton Plasma Physics Laboratory), Eric Shi (Lawrence Livermore 
 National Laboratory), Manaurae Francisquez (Princeton Plasma Physics Labor
 atory), and James Juno (University of Maryland)\n\nWe use an advanced comp
 utational framework called Gkeyll to simulate plasma turbulence in the edg
 e of magnetic confinement fusion experiments. In these experiments, charge
 d particles gyrate quickly around magnetic field lines. When time scales o
 f interest are much greater than the gyration period and the wavelengths o
 f disturbances parallel to field lines are much larger than the gyro-radiu
 s, one can average over the gyro-period of the plasma particles and effect
 ively model them as rings. This gyrokinetic formulation reduces the partic
 les’ probability density function from six dimensions (three spatial and t
 hree velocity) to five (three spatial and three velocity) and is the model
  we use in our research. Gkeyll uses the discontinuous Galerkin (DG) finit
 e element method, which combines the benefits of finite element methods, s
 uch as high-order accuracy, with those of finite volume methods, including
  locality of data. DG also allows for conservative schemes. We have benchm
 arked the code by modeling the Texas Heliamk, a basic plasma physics exper
 iment, and comparing with experimental data. We have also developed a new 
 and faster version of the code with improved conservation properties. This
  research demonstrates Gkeyll's progress toward 5D simulations of the edge
  region of fusion devices.\n\nTag: Diversity, Education, Hot Topics\n\nReg
