Papers in PRL (and all of PR, I think) are free if you're using a public library WiFi, in case that helps. This is for magnetic fusion. I think you're right, it's an incremental improvement in a calculation of the screening effects of ions.

Note that any fusion reactor will have significant issues around radioactive waste disposal, proliferation, etc., regardless of what journalists say¹. ¹http://thebulletin.org/fusion-reactors-not-what-they%E2%80%99re-cracked-be10699 http://thebulletin.org/fusion-reactors-not-what-they%E2%80%9...
