The standard GAMMA 10 configuration is characterized by high ellipticity of the anchor fans, where the thickness of plasma is 2.5cm only. Thin anchor fans are probable places of fast radial transport. Possible way to check this assumption is to diminish the ellipticity. This task is complicated by several requirements to magnetic configuration: symmetrization of magnetic field, MHD stability, ensuring of proper conditions for ICRH and ECRH.
In the paper the calculations of GAMMA 10 magnetic field and MHD stability are presented. As a result of calculations the range of currents suitable for stable symmetrized configurations with low ellipticity was determined.
