ELAHI, A. Salar  and  GHORANNEVISS, M.. Measurement of the plasma boundary shift and approximation of the magnetic surfaces on the IR-T1 Tokamak. Braz. J. Phys. [online]. 2010, vol.40, n.3, pp.323-326. ISSN 0103-9733.

In this research we measured the plasma boundary shift using array of magnetic pick- up coils on the IR- T1 tokamak. Also we approximated the magnetic surfaces by an equilibrium calculation. Firstly, four magnetic probes were designed, constructed, and installed on outer surface of the IR- T1 tokamak chamber and then plasma boundary displacement measured from them. On the other hand, magnetic surfaces approximated by equilibrium calculation of the Grad- Shafranov equation based on expansion of free functions as quadratic in flux function.

Keywords : Tokamak; Plasma Boundary Shift; Magnetic Surfaces.
