Beschreibung:
Spheromaks are easily formed, self-organized magnetized plasma configurations that have intrigued plasma physicists for over two decades. Sometimes called magnetic vortices, magnetic smoke rings, or plasmoids, spheromaks first attracted attention as a possible controlled thermonuclear plasma confinement scheme, but are now known to have many other applications.
Basic concepts; magnetic helicity; relaxation of an isolated configuration to the Taylor State; relaxation in driven configurations; the MHD energy principle, helicity, and Taylor States; survey of spheromak formation schemes; classification of regimes - an imperfect analogy to thermodynamics; analysis of isolated cylindrical spheromaks; the role of the wall; analysis of driven spheromaks - strong coupling; helicity flow and dynamos; confinement and transport in spheromaks; some important practical issues; basic diagnostics for spheromaks; applications of spheromaks; solar and space phenomena related to speromaks.
