Fusion Plasma Physics and ITER – An Introduction (2/4)

"Physics of Tokamak Plasmas," DJ Campbell (detalles de la física de la fusión) Fusion Plasma Physics and ITER - An Introduction (2/4) Campbell, David (speaker) (Particle Physics) CERN. Geneva (Academic Training Lecture Regular Programme ; 2010-2011) Academic Training Lecture Regular Programme The second lecture will explore some of the key physics phenomena which govern the behaviour of magnetic fusion plasmas and which have been the subject of intense research during the past 50 years: plasma confinement, magnetohydrodynamic stability and plasma-wall interactions encompass the major areas of plasma physics which must be understood to assemble an overall description of fusion plasma behaviour. In addition, as fusion plasmas approach the "burning plasma" regime, where internal heating due to fusion products dominates other forms of heating, the physics of the interaction between the α-particles produced by DT fusion reactions and the thermal "background" plasma becomes significant. This lecture will also introduce the basic physics of fusion plasma production, plasma heating and current drive, and plasma measurements ("diagnostics"). cdsweb.cern.ch

Fusion Plasma Physics and ITER – An Introduction (1/4)

"Fusion Plasma Physics in Magnetic Fusion," DJ Campbell (la física básica de la fusión) Fusion Plasma Physics and ITER - An Introduction (1/4) Campbell, David (speaker) (ITER Organization, France) CERN. Geneva (Academic Training Lecture Regular Programme ; 2010-2011) Academic Training Lectures Academic Training Lecture Regular Programme Abstract In November 2006, ministers representing the world's major fusion research communities signed the agreement formally establishing the international project ITER. Sited at Cadarache in France, the project involves China, the European Union (including Switzerland), India, Japan, the Russian Federation, South Korea and the United States. ITER is a critical step in the development of fusion energy: its role is to confirm the feasibility of exploiting magnetic confinement fusion for the production of energy for peaceful purposes by providing an integrated demonstration of the physics and technology required for a fusion power plant. The ITER tokamak is designed to study the "burning plasma" regime in deuterium-tritium (DT) plasmas by achieving a fusion amplification factor, Q (the ratio of fusion output power to plasma heating input power), of 10 for several hundreds of seconds with a nominal fusion power output of 500MW. It is also intended to allow the study of steady-state plasma operation at Q≥5 by means of non-inductive current drive, preparing the way for fusion power plants to operate continuously. ITER relies on the "tokamak <b>...</b>
