Shape Control in Tokamaks

The need of achieving always better performance in present and future tokamak devices has pushed plasma control to gain more and more importance in tokamak engineering. When high performance and robustness are required, it is essential to adopt a model-based approach to design a control system. In this paper we introduce the basics of plasma current, shape position control in tokamaks. As examp...

Integrated Plasma Control for High Performance Tokamaks

Sustaining high performance in a tokamak requires controlling many equilibrium shape and profile characteristics simultaneously with high accuracy and reliability, while suppressing a variety of MHD instabilities. Integrated plasma control, the process of designing high-performance tokamak controllers based on validated system response models and confirming their performance in detailed simulat...

Plasma Frequency Radiation in Tokamaks

Radiation from relativistic runaway electrons is considered as a source for plasma frequency radiation in tokamaks. Two specific emission mechanisms, Cerenkov emission, and radiation produced by nonlinear coupling of plasma and acoustic waves, are studied. In many cases the Cerenkov emission provides a reasonable spectral fit. It can also be used to measure the runaway current, and to est'imate...

Simulating Plasma Turbulence in Tokamaks

The development of magnetic fusion energy is a continuing national priority. Present day toroidally confined plasma experiments (tokamaks) are producing fusion power comparable to the input power needed to heat the plasma (Pfusion ≈ 0.3Pin). One of the basic physics problems is to understand turbulent transport phenomena, which cause particles and energy to escape the confining magnetic fields....

Experimental Hysteresis Identification and Micro-position Control of a Shape-Memory-Alloy Rod Actuator

In order to exhaustively exploit the high-level capabilities of shape memory alloys (SMAs), they must be applied in control systems applications. However, because of their hysteretic inherent, dilatory response, and nonlinear behavior, scientists are thwarted in their attempt to design controllers for actuators of such kind.  The current study aims at developing a micro-position control system ...
