Tungsten Cathode Completed Focus Fusion

• arclein

After carefully testing and measuring the cathode, the LPPFusion team expect to install it in the FF-1 plasma focus device and begin experiments during March. The tungsten electrodes (the anode is already installed) are expected to totally stop vaporization of the electrode materials due to arcing, since they are each made of a single piece of metal, with no joins for arcs to form. In addition the tungsten material, which has the highest melting point and one of the highest boiling points of any material, is expected to eliminate additional vaporization from high energy (runaway) electrons during the earliest moments of the electrical discharge. Together, this should end the large amounts of impurities in the plasma, allowing the achievement of far higher fusion yields
