Alpha Particle Induced Magnetoacoustic Instability in a Thermonuclear Plasma
We show that in a thermonuclear plasma the magnetosonic wave propagating normal to the magnetic field can be unstable. The growth rate is small, however, and the wave is easily stabilized by perpendicular thermal conduction. IN A FULLY IGNITED thermonuclear plasma the fusion energy production balances the various energy losses and the fusion reaction is self-sustaining. The product ions (alpha ...
متن کاملA time-delay approach for the modeling and control of plasma instabilities in thermonuclear fusion
This letter presents a summary of [1], where we investigated the stability problems and control issues that occur in a reversedfield pinch (RFP) device, EXTRAP-T2R, used for research in fusion plasma physics and general plasma (ionized gas) dynamics. The plant exhibits, among other things, magnetohydrodynamic instabilities known as resistive-wall modes (RWMs), growing on a time-scale set by a s...
متن کاملRadiowave propagation in a statistically inhomogeneous plasma
The present work investigates the propagation of a radio pulse in an unmagnetized, statistically inhomogeneous plasma causing regular refraction and anisotropic scattering. Using the framework of geometrical optics, a Fokker-Planck equation is derived and integrated within a two-moment approximation. The method allows a continuous transition from weak to strong angular scattering and yields pul...
متن کاملA low-level activation technique for monitoring thermonuclear fusion plasma conditions.
Optimisation of the confinement and sustainability of a thermonuclear plasma requires methods to monitor processes in the plasma. In this work three materials were used as activation targets (Ti, MgF2 and a TiVAl compound). They were placed inside the joint European Torus (JET) vacuum chamber. Certain gamma-ray emitting radionuclides (7Be, 54Mn, 56Co, 57Co, 58Co and 46Sc) were measured using ul...
متن کاملThe International Thermonuclear Experimental Reactor and the Nuclear Weapons Proliferation Implications of Thermonuclear-Fusion Energy Systems
This report contains two parts: (1) A list of “points” highlighting the strategic-political and military-technical reasons and implications of the very probable siting of ITER (the International Thermonuclear Experimental Reactor) in Japan, which should be confirmed sometimes in early 2004. (2) A technical analysis of the nuclear weapons proliferation implications of inertialand magnetic-confin...
