There has been quite a few books published on this topic recently. CUP themselves have put out quite a few. I think this one stands out as the one for engineers, because it addresses plasma physics of course, but also engineering issues for building machines. It's not easy reading because the topic is hard, but the author does a good job of explaining things. I would recommend this book as point of entry in the topic for students of engineering or practising engineers needing an entry into the field.
