Diagnosing the state of an unruly plasma
The narrow, high-voltage gap between the positive and negative electrodes in a pulsed-power diode is a hostile environment. Intense electric and magnetic fields, restricted to a small volume, tear matter apart to produce an extremely hot, unruly plasma of ions and electrons. Such extreme conditions make it difficult to monitor what's happening inside the diode--the kind of fundamental information needed for learning how to generate ion beams with the right characteristics to initiate and drive thermonuclear fusion in tiny fuel pellets.
