- Abstract
- This overview of results from the MST reversed field pinch program summarizes physics im-
portant for the advancement of the RFP as well as for improved understanding of toroidal magnetic
confinement in general. Topics include energetic particle effects, 3D helical equilibria,
and density
limit studies, microturbulence, ion heating, and magnetic self-organization physics. With neutral
beam injection, several bursty energetic particle (EP) modes are observed. The profiles of the magnetic
and density fluctuations associated with these EP-modes are measured using an FIR interferometer-
polarimeter. Equilibrium reconstructions of the quasi-single-helicity 3D helical state are provided
by the V3FIT code that now incorporates several of MST's advanced diagnostics. A predator-prey
theoretical model based on sheared flow and/or magnetic field has been developed that captures
key QSH dynamics. Upgraded pellet injection permits study of density and
limits over MST's full
range of operation, and an MST-record line-average density of

Gyrokinetic simulations (GENE) based on experimental toroidal equilibrium reconstructions predict
unstable trapped electron modes. Nonlinear simulations show that the \"Dimits shift\" is large and
persists at finite
. Experimentally, small-scale density fluctuations are detected in improved confine-
ment plasmas. Impurity ion temperature measurements reveal a charge-to-mass-ratio dependence in
the rapid heating that occurs during a sawtooth crash. Also, a toroidal asymmetry in the ion temper-
ature is measured, correlated with 3D magnetic structure associated with tearing modes. Magnetic
self-organization studies include measurements and modeling of the dynamo emf in standard RFP
operation as well as with an applied ac inductive electric field to investigate the dynamics of oscillating
field current drive (OFCD). Extended MHD computation for standard RFP conditions using NIMROD
predicts dynamical coupling of current and plasma flow relaxation. The dynamo emf has also been
measured when OFCD is applied, strengthening the understanding of and possibility for steady-state
current sustainment using inductive current drive. (literal)
