The basic problems of Tokamak-15 electromagnetic system (EMS) elaboration are discussed. The EMS design is described, its main component parameters and features are presented. The R and D program for the EMS design including its most complicated component, the superconducting toroidal field system (TF system), is considered. Post-assembly EMS tests comprising the achievement of a toroidal field nominal value and plasma discharges are described.

In this paper the main objectives and research programme of T-15 are given: producing and investigation of the plasma with reactor-relevant parameters sufficient for reliable extrapolation to ignited plasma; testing of the engineering and technology, appropriate for a fusion tokamak reactor, on the operating device. The basie features of the facility are described and T-15 research programme is presented.

A facility for mechanical testing of a magnet insulation sample is described which is part of the ITER related R and D program. The facility is aimed at testing isolated conductors and different materials for mechanical and electrical strength at cryogenic temperature and in vacuum. The maximum value of mechanical load is 900 kN; the voltage is 135 kV. The facility comprises an electromagnetic press, including two superconducting coils and the mechanical system

The superconducting magnet systems of the International Thermonuclear Experimental Reactor (ITER) will be potential users of advanced cryogenic materials and components (high-field and high-current density superconductors, high strength cryogenic steels, radiation tolerant insulation etc.) on a rather large scale and will require a highly reliable and economically effective cryogenic system with the capacity about 100 kW at 4.5 K. The paper describes the main design features of the ITER magnet systems and summarizes the operating conditions, requirements and critical issues for the magnet materials and components. A brief review of the ITER magnet material R&D programme being carried out in our country is presented.

Materials on clinical application in cardiosurgery of Soviet-made apparatus for extracorporeal circulation, models (formula: see text) and (formula: see text) are presented. Modification of these apparatus aimed at securing separate sterilization of its pumping units and setting them in place as a complete aggregate is described. This is achieved by providing the pumping assembly with articulated lock bolts and locating grips diametrically on the faceplate of the pump over which, to temporarily fix the cover with distributing valves and the pump's diaphragms, a rubber plait is hooked on.
