Influence of the Plasma Shape on the Pinch Effect on Axisymmetric Tokamaks

Numerical calculations of Ware-pinch effect in general plasma configuration are considered. Though analytical treatment of Ware-pinch in plasma configurations including ellipticity and triangularity were presented previously, however, applications of these equations to actual tokamaks are very important and not presentations have been done until now using this technique. Curvilinear coordinates described in previous papers are used [1-4]. This work is justly dedicated to fill out this matter and numerical calculations have been carried out for different tokamaks with different geometry parameters. First, the effect of ellipticity is considered and later triangularity influences are also included in our calculations. Graphics results will be presented. \\[4pt] [1] P. Martin, E. Castro and M.
