Permanent Magnet Penning Trap
Daniel C. Barnes, Daniel R. Knapp
The Penning trap has been investigated as the basis of a small nuclear fusion reactor using a superconducting solenoid magnet. To extend this investigation, we designed, constructe…
Finite spatial-grid effects in energy-conserving particle-in-cell algorithms
D. C. Barnes, L. Chacon
Finite-grid (or aliasing) instabilities are pervasive in particle-in-cell (PIC) plasma simulation algorithms, and force the modeler to resolve the smallest (Debye) length scale in…
Geometric scalings for the electrostatically driven helical plasma state
Cihan Akçay, John M. Finn, Richard A. Nebel +1
A new plasma state has been investigated [C.~Akcay, J.~Finn, R.~Nebel and D.~Barnes, Phys.~Plasmas , 052503 (2017)], with a uniform applied axial magnetic field in a p…
Properties of the electrostatically driven helical plasma state
Cihan Akçay, John M. Finn, Richard A. Nebel +2
A novel plasma state has been found [C.~Akçay, J.~Finn, R.~Nebel and D.~Barnes, Phys.~Plasmas \textbf{24}, 052503 (2017)] in the presence of a uniform applied axial magnetic field…
Electrostatically driven helical plasma state
Cihan Akçay, John M. Finn, Richard A. Nebel +1
A novel plasma state has been found in the presence of a uniform applied axial magnetic field in periodic cylindrical geometry. This state is driven electrostatically by helical el…
An efficient mixed-precision, hybrid CPU-GPU implementation of a fully implicit particle-in-cell algorithm
Guangye Chen, Luis Chacón, Daniel C. Barnes
Recently, a fully implicit, energy- and charge-conserving particle-in-cell method has been proposed for multi-scale, full-f kinetic simulations [G. Chen, et al., J. Comput. Phys. 2…
