Steady state versus pulsed tokamak reactors

Characteristics of Rf-driven Steady State Tokamak Power Reactors

The use of lower hybrid waves for current drive in steady state tokamak power reactors is studied. Constraints imposed by rf wave propagation are considered in detail. The effect of decoupling of electron and ion temperatures is studied and is found to enhance significantly the ratio of fusion power to dissipated power. Tradeoffs for parameters of rf driven steady state reactors are determined....

Comparison of pulsed three‐dimensional CEST acquisition schemes at 7 tesla: steady state versus pseudosteady state

PURPOSE To compare two pulsed, volumetric chemical exchange saturation transfer (CEST) acquisition schemes: steady state (SS) and pseudosteady state (PS) for the same brain coverage, spatial/spectral resolution and scan time. METHODS Both schemes were optimized for maximum sensitivity to amide proton transfer (APT) and nuclear Overhauser enhancement (NOE) effects through Bloch-McConnell simul...

A Steady-state Module for Modeling Anaerobic Biofilm Reactors

−− A steady state model of an anaerobic methanogenic biofilm reactor-module that accounts for the biological interactions of four microbial groups, ionic equilibrium in solution, gas-liquid transfer phenomena and biofilm processes is presented. The model consists of a continuous stirred tank reactor type that allocates an inert support material, whose specific surface is taken into account. The...
