The tokamak TSP-AST concept

The TSP tokamak—Russian fusion project based on very powerful adiabatic heating by compression (900 MJ power supply per pulse)—was entered into exploitation in 1987. The study program with circular cross-section plasma was carried out on the machine from 1988 to 1992. The TSP tokamak program object lost urgency for today. So, modernization of TSP tokamak is planned as creation of new version of machine, which will allow from one hand to use the basic infrastructure of existing machine and unique systems of the pulse power supplies and on another hand to execute greatest possible amount of researches on the fusion basic problems. This modernization was named TSP-AST tokamak (TSP in the mode of advanced or adiabatical spherical tokamak). In the paper the purposes and tasks of the machine, basic parameters of operations regimes and plasma discharge scenarios are submitted. The design version of the basic units of machine (magnet, vacuum vessel) are shown. The calculations results of tensile strength of the machine basic units are given.
