We use a basic magnetic toroidal field configuration with shear plus overlapping island chains creating magnetic ergodic layer. We would like to use this apparatus for solving two physical problems. Firstly for an estimate of generation of electric field in edge plasma caused by addition of “ergodic coils”, which could serve as a mechanism for mitigation of ELMs and is will be studied on the COMPASS tokamak. Secondly we want to use the apparatus for tracing the influence on runaway electrons (energy 10 MeV) in the presence of magnetic field generated by Error Field Correction Coils (EFCCs) as are installed on JET Tokamak.
