Abstract
- Plasma energy, poloidal beta, plasma pressure, plasma temperature, plasma resistance, and plasma effective atomic number are important parameters in tokamak plasma experiments. In this paper, we present a theoretical and experimental approach especially based on diamagnetic loop for measurement of these parameters in the presence of resonant helical field (RHF) and biased electrode in IR-T1 tokamak. For this purpose, an electrode biasing system and a diamagnetic loop with its compensation coil designed, constructed, and installed on the IR-T1. In addition, we measured the plasma current, plasma voltage, and the plasma density from the Rogowski coil, the poloidal flux loop, and the Langmuir probe measurements, respectively. Experimental results show that the addition of a relatively small amount of RHF with \(L=2\) and \(L=3\) modes could be effective for improving the quality of tokamak plasma discharge by creating the steady-state plasma.
