On Convex Subcomplexes of Spherical Buildings and Tits’ Center Conjecture [PDF]

, 2009
In this thesis we study convex subcomplexes of spherical buildings. In particular, we are interested in a question of J. Tits which goes back to the 50’s, the so-called Center Conjecture.

Neutronics analysis of spin-polarized fuel in spherical tokamaks

Nuclear Fusion
The effect of spin-polarized deuterium–tritium fuel on the blanket, magnets, and surrounding structures is analyzed for a spherical tokamak fusion power plant.

Nonlinear MHD Simulations of Spherical Tokamak and Helical Plasmas

"Nonlinear magnetohydrodynamic (MHD) simulations on relaxation phenomena in a spherical tokamak and a helical plasma, including three-dimensional (3D) equilibrium computations, are executed in full toroidal geometries.

Observation of a new pedestal stability regime in MAST Upgrade H-mode plasmas

Nuclear Fusion
The first pedestal stability and structure analysis on the new MAST Upgrade (MAST-U) spherical tokamak H-mode plasmas is presented. Our results indicate that MAST-U pedestals are close to the low toroidal mode number ( n ) peeling branch of the peeling ...

Collisional transport of trace impurity ions and the role of the radial electric field in spherical tokamak plasmas [PDF]

The mitigation and control of impurities, or non-fuel ions, in tokamak plasmas is vital for reducing energy losses and an understanding of impurity transport is required in order to predict the performance of present and future tokamak devices.

Large Potential Change Induced by Pellet Injection in JIPP T-IIU Tokamak Plasmas

, 1995
"A large, rapid change in the local plasma potential is found to be induced by off-axis hydrogen ice-pellet injection into a tokamak plasma. The polarity of the rapid change is reversed when the pellet is injected into the upper and lower halves of the ...
