Here is one site with some of their papers put up for free. In the interest of disclosure, I am not a part of this group but I do know their work reasonably well.

I’m sad to say that experience is expensive. I pay $30 or more per article. I guess the question one must ask is the level of devotion to learning the subject. Just a warning, these are peer-reviewed publications. The authors expect some minimum understanding of plasmas and little is provided to help you in the journal articles other than references to other articles and more money spent. If you are seeking a basic appreciation of the subject, popular science type literature on the plasma focus exists and some of it is linked on this site. I look forward to the day when the pay walls fall down so everyone can see all the different interpretations of available data and decide from themselves what is the best interpretation.
