The findings of a new study by University of Iowa theoretical physicist Michael Flatte could play a role in the development of future generations of smaller, more energy-efficient computers and e...
Efficiency of LH+EC Current Drive in Tokamaks Featuring an Internal Transport Barrier
LH+EC Current Drive Tokamaks an Internal Transport Barrier
2010/10/14
In the present paper we study the effects due to the occurrence of radial transport of particles in a tokamak on the efficiency of current drive due to combined action of lower hybrid waves and electr...
Experimental Characterization of a Low-Current Cutting Torch
Experimental Characterization a Low-Current Cutting Torch
2010/10/26
An experimental characterization of a low-current (30-40 A) cutting torch is presented. To avoid contamination of the plasma arc by removed anode material, a rotating steel cylinder was used as the an...
Surface Charges and External Electric Field in a Toroid Carrying a Steady Current
Surface Charges External Electric Field a Steady Current
2010/10/27
We solve the problem of a resistive toroid carrying a steady azimuthal current. We use standard toroidal coordinates, in which case Laplace’s equation is R-separable. We obtain the electric potential ...
