Plasma Control in Tokamaks. Part 3.1. Plasma Magnetic Control Systems in ITER

2020
The plasma magnetic control systems for ITER (International Thermonuclear Experimental Reactor) are presented. The systems comprise original engineering solutions for plasma position, current and shape control for the two versions of ITER: ITER-1 and ITER-2, including those designed in V. A. Trapeznikov Institute of Control Sciences of the RAS.

Plasma magnetic control for DEMO tokamak using MPC

2022 IEEE Conference on Control Technology and Applications (CCTA), 2022
This paper proposes a model predictive controller (MPC) designed to tackle the magnetic control of the DEMO plasma. DEMO is an ambitious EU project aimed at the construction by 2050 of a tokamak demonstrating that energy from nuclear fusion can be conveniently commercially used.

Magnetic field control of reactive plasma etching

Applied Physics Letters, 1979
The application of a magnetic field to control the spatial distribution of chemical species in reactive plasma etching produces a situation in which either etching or deposition can occur. In a low-voltage hot-filament triode configuration in which the plasma is confined by an externally applied magnetic field, Si samples are subjected to a CF4 plasma.

Basic issues on tokamak plasma magnetic control

2008 47th IEEE Conference on Decision and Control, 2008
Aim of this paper is to give an introductory overview of what is typically called the ?plasma magnetic control problem? in tokamak machines. Tokamaks are devices with a toroidal symmetry; these devices are, at the present, the most promising for producing nuclear fusion between two atoms on earth.

Plasma magnetic robust control in tokamak-reactor

Proceedings of the 45th IEEE Conference on Decision and Control, 2006
The paper is devoted to the development of two-loop plasma position, current and shape control system in tokamak-reactor. The Hinfin approach is used for the design of SISO and MIMO feedback controllers. In the procedure of controllers design the MIMO linear plant model (plasma in tokamak) DINA-L was used.

A magnetically controlled arc for plasma torch incineration

IEEE Conference Record - Abstracts. 1996 IEEE International Conference on Plasma Science, 2002
Summary form only given. With the ever increasing problems of chemically hazardous and radioactive waste produced from federal, commercial, medical, academic, and nuclear utility sources, a safe means of waste elimination or disposal is desired. Plasma torches represent an electrical arc technology that possesses certain advantages in radioactive and ...

The Madistor-A Magnetically Controlled Semiconductor Plasma Device

Proceedings of the IRE, 1962
The madistor is a new active device which makes use of the effects of a magnetic field on an injection plasma in a semiconductor. The formation of an injection plasma has been observed in p-type InSb at temperatures below 100°K as donor traps become saturated by electrons injected through a forward biased n+p junction. In an appropriately designed n+pp+
