An economic magnetic fusion reactor favours a high ratio of plasma kinetic pressure to magnetic pressure in a well-confined, hot plasma with low thermal losses across the confining magnetic field. Field-reversed configuration (FRC) plasmas are potentially attractive as a reactor concept, achieving high plasma pressure in a simple axisymmetric geometry. Here, we show that FRC plasmas have unique...

Alan Turnbull March 2009 General Atomics Inc. and The ARIES Group The present White Paper is the second of three concerning the issue of plasma control, which is taken here to include control of the power flow in addition to the main plasma parameters and profiles. The first paper, “Control of the Plasma and the Power Flow in a Reactor”, identifies the individual issues that need to be addresse...

Intense deposition of energy in short times on fusion reactor components during a plasma disruption may cause severe surface erosion due to ablation of these components. The exact amount of the eroded material is very important to the reactor design and its lifetime. During the plasma deposition, the vaporized wall material will interact with the incoming plasma particles and may shield the res...

Today the applications of nuclear physics span a very broad range of topics and fields. This review discusses a number of aspects of these applications, including selected topics and concepts in nuclear reactor physics, nuclear fusion, nuclear non-proliferation, nuclear-geophysics, and nuclear medicine. The review begins with a historic summary of the early years in applied nuclear physics, wit...

The solution of the heat conduction probem in moving boundary conditions is very important in predicting accurate thermal behavior of materials when very high energy deposition is expected. Such high fluxes are encountered on first wall materials and other components in fusion reactors. A numerical method has been developed to solve this problem by the use of the Green's function. A comparison ...

We find the solutions of the Dirac equation for two plane waves (laser beams) and we determine the modified Compton formula for the scattering of two photons on an electron. The practical meaning of the two laser beams is, that two laser beams impinging on a target which is constituted from material in the form a foam, can replace 100-200 laser beams impinging on a normal target and it means th...

Nuclear fusion control, and specifically plasma control, represents one of the newest and more promising applications of Control Engineering, with increasing interest in the control community. In this paper it is made a control-oriented review of the state of the art of nuclear fusion techniques. For this purpose, a comprehensive description of the fusion process is provided, focusing in the mo...

It is demonstrated that a magnetic island chain formed by a saturated tearing instability in a toroidal magnetic fusion device can lock to a special class of externally generated magnetic perturbation in a stabilizing phase. The theoretical apparatus needed to design such perturbations is outlined. These special perturbations—which are termed ‘‘designer’’ error fields—could be used to control t...
