DIII-D Tokamak Quadruples fusion rate by spinning plasma

I bought a copy of an Australian/UK magazine "New Scientist" dated 14th of July. On page four they mention that the DIII-D Tokamak has been able to spin a plasma successfully for long periods of time by correcting tiny imperfections in the magnetic containment field with feedback loop corrected magnets. The upshot of that was it allowed Ronald Stambaugh (US National Fusion Facility) to double the plasma pressure and quadruple the fusion rates previously achieved.
I had a bit of a surf on the net and found an abstract of one of his papers: "Higher fusion power gain with current and pressure profile control in strongly shaped DIII-D tokamak plasmas". It mentions they have a an input to output power Q of 0.0015 which sounds pretty good to me!. It sounds like pretty interesting reading but I can only get hold of the abstract and not the actual paper.
