Abstract

The VISIONI plasmatron is a plasma simulator dedicated to thermonuclear fusion material studies. Theplasma is confined by means of a strong multipole cusp magnetic field produced by rectangular per-manent samarium–cobalt magnets positioned just outside of the plasma chamber. The magnitude ofthis field as a function of the location in the plasma chamber is an important input for the ongoingplasma and material migration computer simulations for VISIONI. In this work the magnetic field in theVISIONI plasma chamber was calculated analytically. The calculated results were benchmarked and ver-ified experimentally by Hall probe measurements. The analytical formulas are very convenient for use indifferent simulation codes.
