I have found this book immensely useful and a pleasure to read as a senior undergraduate engaging in summer research in fusion. It is perfect for learning basic plasma physics in the context of fusion, which may not be easy with books that discuss plasma more generally (such as F.F. Chen's introductory book, though that is very good). The writing is highly structured and clear physical pictures are presented.

There is a nice opening section on energy options and where fusion fits in, and there are sections on fusion reactor types and technologies.
