Feedforward and feedback control of locked mode phase and rotation in DIII-D with application to modulated ECCD experiments
Wilkie Choi, R. J. La Haye, M. J. Lanctot +4
The toroidal phase and rotation of otherwise locked magnetic islands of toroidal mode number n=1 are controlled in the DIII-D tokamak by means of applied magnetic perturbations of…
Overdense microwave plasma heating in the CNT stellarator
K. C. Hammond, R. R. Diaz-Pacheco, A. Koehn +2
Overdense plasmas have been attained with 2.45 GHz microwave heating in the low-field, low-aspect-ratio CNT stellarator. Densities higher than four times the ordinary (O) mode cuto…
High- equilibrium and ballooning stability of the low aspect ratio CNT stellarator
K. C. Hammond, S. A. Lazerson, F. A. Volpe
The existence and ballooning-stability of low aspect ratio stellarator equilibria is predicted for CNT with the aid of 3D numerical tools. In addition to having a low aspect ratio,…
Space- and Time-resolved Resistive Measurement of Liquid Metal Wall Thickness
S. M. H. Mirhoseini, F. A. Volpe
In a fusion reactor internally coated with liquid metal, it will be important to diagnose the thickness of the liquid at various locations in the vessel, as a function of time, and…
Onion-peeling inversion of stellarator images
K. C. Hammond, R. Diaz-Pacheco, Y. Kornbluth +2
An onion-peeling technique is developed for inferring the emissivity profile of a stellarator plasma from a two-dimensional image acquired through a CCD or CMOS camera. Each pixel…
Statistical analysis of = 2/1 locked and quasi-stationary modes with rotating precursors at DIII-D
R. Sweeney, W. Choi, R. J. La Haye +4
A database has been developed to study the evolution, the nonlinear effects on equilibria, and the disruptivity of locked and quasi-stationary modes with poloidal and toroidal mode…
