Plasma Position

The mission of this script is to process data from Mirnov coils, determine plasma position and thus help with plasma stabilization. Mirnov coils are type of magnetic diagnostics and are used to the plasma position determination on GOLEM. Four Mirnov coils are placed inside the tokamak 93 mm from the center of the chamber. The effective area of each coil is $A_{eff}=3.8\cdot10^{-3}$ m. Coils $mc_9$ and $mc_1$ are used to determination the horizontal plasma position and coils $mc_5$ and $mc_{13}$ to determination vertical plasma position.
