Simultaneous Simple Measurements of Tokamak Plasma Parameters Especially Based on Plasma Diamagnetic Effect

Abstract

Determinations of poloidal beta, internal inductance, plasma energy, plasma pressure, plasma temperature, plasma resistance, plasma effective atomic number, and plasma energy confinement time are essential for tokamak plasma experiments. In this paper an experimental methods especially based on diamagnetic loop (toroidal flux loop) for measurements of these parameters are presented. For this purposes a diamagnetic loop with its compensation coil and also an array of magnetic probes designed, constructed, and installed on outer surface of the IR-T1 tokamak. Also in this work we obtained the Shafranov parameter, plasma current, plasma voltage, and the plasma density from the magnetic probe, Rogowski coil, poloidal flux loop, and the Langmuir probe measurements, respectively.
