Abstract
A compact spherical tokamak MEPhIST (MEPhI Spherical Tokamak) aimed at educational, demonstration and research purposes is under development at Institute of Laser and Plasma technologies (LaPlas) at NRNU MEPhI. The main purposes are training in the field of controlled thermonuclear fusion for Russian installations (T-15MD, T11-M and others) and the international ITER reactor, as well as solving innovative problems in the field of fusion technologies. An important feature of this project is the most possible digitalization of the installation in order to provide a remote access for students of other universities specializing in the field of fusion technologies with magnetic plasma confinement. With the successful implementation of the project to create a reliable tokamak, this installation will be used to solve a number of urgent scientific and technological problems: acceleration of lithium technologies development, studies of plasma confinement in a spherical tokamak, development of high-frequency (RF) technologies (microwave preionization and steady-state RF current drive) and to develop in situ methods for analyzing plasma-surface interaction. At this stage, the design of the educational, demonstration and research tokamak MEPhIST has been carried out, the concepts of diagnostic systems and additional heating of the plasma have been developed, the production of a vacuum chamber and elements of an electromagnetic system has been started.
