    Best Plasma physics textbooks suggestions

    Hey all, I'm looking for a good introductory book (I've had Physics 1 and 2, some thermo and modern) on plasmas because I will be doing research this summer in plasma physics. I have heard Francis Chen's "Introduction to Plasma Physics" is a good start. Any reviews on this book?

    Is Plasma Physics Still a Viable Field for Research?

    The consensus among a number of my (undergrad) peers is that the field of plasma physics is relatively dead and that nothing ground breaking has been done a long while. I would have liked to go to grad school for this but not as much if this is true.

    Does plasma density affect the frequency of electrostatic oscillations?

    How Do Magnetic Mirrors Affect Conservation and Torque in Plasma Physics?

    I'm taking a short course in plasma physics, and we've covered quickly the magnetic mirror. So the idea is that an ion, say a proton, moves along a helical path along parallel B-field lines - say in z-direction. Then the lines converge towards the z-axis, forming a shape like a bottleneck, with...
