Tungsten Anode Goes Into FF-1; Aluminum Cathode Model Is Checked

story2b

October 10, LPPFusion team members Eric Lerner, Hamid Yousefi and Tony Ellis lifted the tungsten anode into place on top of the FF-1 dense plasma focus experimental device (figure 1). The anode had previously been attached to its steel connecting plate (see September report) and was temporarily attached to a metal carrying rod for insertion…

Re-Assembly Begins of FF-1 with Tungsten Electrodes

anodediagram

The new tungsten anode has a current connection with the silvered steel plate at the edge indicated to by the blue arrow.  This current connection is below the red O-ring (yellow arrow) that seals the vacuum chamber indicated by the black arrow.  The old current connection was at the location of the red arrow, inside the vacuum chamber…

Nature Magazine Urges More Funding for Aneutronic Fusion

nature 200×200

In a July 23 editorial, Nature magazine has joined the calls to redirect fusion funding to aneutronic fusion—fusion that produces no radioactive waste. Speaking of the difficulties facing the ITER tokamak program, the editorial urged that, “Given these realities, the prudent course for the world’s funding agencies would be to support research into alternative fusion…

Tungsten anode has arrived

anodetungsten

The first of LPP’s new tungsten electrodes, the anode, or inner electrodes, is now complete and has arrived at our Middlesex, NJ lab. The electrode will contribute to greatly reducing the impurities that have prevented high density in our fusion-generating plasmoids. First, it connects to the rest of the circuit outside the vacuum chamber, eliminating…

Digging in the Data—oscillations and x-rays

oscillations

The months that FF-1 is not running have given the LPP research team time to look more deeply at the hundreds of gigabytes of data that the experiments have been generating. One puzzle LPP Electrical Engineer Fred van Roessel looked at was the rapid oscillation in current and voltage that occurs when the machine fires…

LPP and PPRC collaborate on pre-ionization experiments

anode erosion

The FF-1 anode, which is plated with 0.001 inches of silver, shows a ring of erosion near the end of the insulator (which has been removed along with the cathode). On the right side, where deposits have been cleaned away, the copper color shows clearly where a ring of silver has been vaporized and measurements…

Russian DPF beats NIF and hits 30 J with deuterium-tritium

DPFDT

Many news outlets widely—and inaccurately—reported new results from the huge National Ignition Facility (NIF) as achieving the long sought- after goal of breakeven for fusion. What NIF in fact reported was a fusion yield of 17 kJ, more than the energy actually absorbed by the fuel pellet. The total input energy to the machine was…
