New Plasma Heating Mechanism to Make Fusion Reactors Safe and Efficient

New Plasma Heating Mechanism to Make Fusion Reactors Safe and Efficient

WIR October 31, 2016 U.S. physicists have proposed a new plasma heating mechanism that prevents interior fusion reactor damage while maximizing energy transfer. Utilizing one of the most important methods for heating plasma, the proposed strategy promises to help prevent damage to the interior surfaces of the reactor, while also keeping a tighter control of … Read more

LPP Fusion’s bootstrapped nuclear fusion plans with shorter Tungsten electrode experiments and next year with Beryllium

Next Big Future October 30, 2016 The recently-completed set of experiments with LPPFusion’s FF-1 device, combined with discussions with colleagues at the International Center for Dense Magnetized Plasma (ICDMP) conference in Warsaw, have produced a greater understanding of the ways impurities are produced in our device and how to reduce them. LPPFusion’s research team has … Read more

Close control of plasma rotation improves stability in fusion reactors

Close control of plasma rotation improves stability in fusion reactors

theEngineer.com By Stuart Nathan 28th October 2016 Stability map of fusion plasma in NSTX. Blue is stable and red is unstable. As the plasma decreases collisionality and increases rotation in time it transitions into an unstable region Previous plasma physics theory held that making the plasma rotate would keep it stable. However, Jack Berkery and … Read more

Breakthrough in Z-pinch implosion stability opens new path to fusion

Breakthrough in Z-pinch implosion stability opens new path to fusion

Scienmag October 27, 2016 Credit: Sandia National Laboratories Using magnetic field thermal insulation to keep plasmas hot enough to achieve thermonuclear fusion was first proposed by the Italian physicist Enrico Fermi in 1945, and independently a few years later by Russian physicist Andrei Sakharov. An approach known as magneto-inertial fusion uses an implosion of material … Read more

Nuclear fusion project leader laments ‘uncontrollable’ political forces

Nuclear fusion project leader laments ‘uncontrollable’ political forces

EurActive Oct 26, 2016 Creating an experimental nuclear fusion reactor is an undertaking that has to face both technical and political challenges. Bernard Bigot, director general of the ITER project, told EurActiv Spain that the political forces are “more uncontrollable” though. Bigot said he was “quite confident” that the technical obstacles facing nuclear fusion technology, … Read more
