| dc.description.abstract | It has been 30 years since the Second Edition. Plasma physics has grown so much
that the temptation is to include all that’s new, but I haven’t done that. This is a book
for those learning plasma physics for the first time and could care less about the fine
points. The basics remain the same, but new areas have arisen: dusty plasmas and
plasma accelerators, for instance, and these subjects had to be added. The semiconductor
industry has sprouted since the 1980s, affecting all our lives. Computer
chips cannot be made without plasmas, but these are partially ionized,
radiofrequency ones, which are new. I’ve spent 25 years helping to make these
industrial plasmas into an interesting subject, one that was previously avoided
because it was too messy. Meanwhile, Al Gore has warned us about global
warming. The best solution to this, and to energy shortage, is of course hydrogen
fusion. With the ITER (International Thermonuclear Experimental Reactor) project
going swimmingly in southern France, we are on schedule to get a fusion reactor by
2050. In laser fusion, the NIF (National Ignition Facility) at Livermore can focus
the entire energy output of the United States onto a pinpoint for a fraction of a
nanosecond to get inertial fusion. It is a technical achievement without peer, but so
far we don’t have a laser that can pulse rapidly enough. Fusion plasma physics was
planned to be Vol. 2 of this textbook; and, in answer to so many questions, it is still
in future plans. The job will be easier now that I have written An Indispensable
Truth, How Fusion Power Can Save the Planet, which includes a chapter on fusion
physics. | en_US |
