Abstract

In this paper we present an experimental investigation of effects of external rotating helical field (RHF) on magnetic field fluctuations around the IR-T1 tokamak chamber. For this purpose, two magnetic pickup coils were designed, constructed, and installed on the outer surface of the IR-T1 tokamak chamber, and then from their output signals after compensation and integration, poloidal and normal components of the magnetic fields measured. Experimental results show that presence of RHF with L = 3 mode can improve the plasma confinement by flatting the plasma current and reducing the amplitude of magnetic field fluctuations.
