Program for scientific and educational investigations on the base of small spherical tokamak Gutta

In Saint-Petersburg state University the modernization of spherical Gutta tokamak is carried out. The aim of the program is to build the research device to study plasma position, shape and current control problems in the tokamak, as well as to assist the scientific and educational programs on various plasma physics problems. Such feature of this device as a relatively small thickness of the vacuum vessel wall made as momentless shell allows changes in the magnetic field in plasma region, to measure the plasma parameters with a minimum delay using electromagnetic diagnostics and changes in toroidal field as necessary.
