Determination of the plasma electron density and equilibrium configuration in TEXT-Upgrade.

摘要

ensity profiles in TEXT-U are obtained using a vertical viewing far-infrared (FIR) interferometer. To obtain the local (inverted) density, we have developed a simple analytic model of the plasma equilibrium configuration which is faster than EFIT (a flux surface reconstruction program) and can be easily computed between discharges. Our approach allows the use of any given plasma LCFS as a fixed boundary The poloidal flux function
