Abstract Text:
The Plasma Science and Innovation Center performs simulations of
collaborating Innovative Confinement Concept (ICC) experiments with the goal of improving predictability. The NIMROD, SEL/HiFi, and PSI-TET codes are used, and modified if necessary, for ICC simulations. Recent studies include: formation studies of the Caltech experiment; formation and relaxation of HIT-SI (Univ of Wash - UW); interchange studies on LDX (M.I.T.); modification of MST tearing-mode by energetic particles [Tharp et al., in preparation], plasma-injector current drive in Pegasus
(Univ of Wisc-Madison); translation and compression of the PHD FRC (UW); equilibrium [Cothran et al., PRL (103)21, 2009] and evolution [Lukin et al., submitted] studies of SSX (Swarthmore College), rotating magnetic field formation of the TCS-U FRC (UW), and flow-shear stabilization of the ZaP flow Z-pinch (UW).

General code development for ICCs include parallel closures for general collisionality (NIMROD [Ji et al., PoP (16), 022312 (2009)]), kinetic-particle effects (NIMROD [Kim et al., PiP (15), 072507 (2008)]), scalable parallel solvers (NIMROD and HiFi), dynamic neutrals including charge-exchange, ionization, and recombination (SEL/HiFi), and general meshing improvements (HiFi and NIMROD).

Output files from all three code have been interfaced to the powerful 3-D visualization program, VisIt [e.g. Hooper et al., PoP (16), 052506 (2009)]. Results from these simulations, as well as the status of the PSI-Center will be presented.
