Anode Heating Studies Advance

  Figure 4. Lerner, center, and engineers Gerry Black, left and Mike Ruthemeyer, right, pause for a photo-op in the midst of discussions of ways to reduce heating of the DPF anode. Black and Ruthemeyer have advanced further in simulations of the anode tip heating, which they confirm is far less for beryllium than tungsten…

Assembly Begins for Beryllium Electrode Experiments

The LPPF research team has begun the re-assembly of the Focus Fusion experimental device for the long-awaited experiments with beryllium electrodes. With the new glove box for handling the electrodes now installed, the first step was to attach new windows to the vacuum chamber (Figure 1). Two of the new larger windows are now protected…

Analysis of Tungsten Data Prepares New Experiments

Right before shutting down to dissemble, the research team took some final ICCD images of the early stages of the pulse, taking images both earlier and later than the series obtained in April. What the images showed is a somewhat more complex history of filament formation and destruction. In the first 75 ns or so,…

New Vacuum Chamber Arrives As Beryllium Assembly Nears

With assembly of the new beryllium electrodes into the Focus Fusion experimental device expected to start within weeks, new equipment is flowing to the LPPF lab in Middlesex, NJ. Our new vacuum chamber, (Fig.1) will provide far better views of the device operation through its three six-inch windows. The chamber has been annealed at high…

Filament Images Confirm LPPFusion Theory

Sequence Filaments

Since 2014, the LPPFusion research team has theorized that heavy metal impurities have limited fusion yields by disrupting the dense filaments that formed early in each shot of the FF-1 plasma focus device. Because the filaments are the first stage of compressing the hot plasma, disrupting them before the main compression phase that forms the…

Upgraded Vacuum Chamber Designed and Ordered

LPPFusion Vacuum Chamber 3D Render

As part of LPPFusion’s preparations for our upcoming experiments with beryllium electrodes and pB11 fuel, we are upgrading our experimental equipment. Research Physicist Syed Hassan has completed a re-design of our vacuum chamber. The key change is to enlarge and reposition the viewing windows. The chamber will now have three six-inch windows, instead of just…

Thermal Study of Electrodes Begins

Initial Simulation of Heating of the Electrodes in FF-1

The cooling of the plasma focus electrodes, especially the anode, is likely to be the toughest engineering problem to be faced in going from a demonstration of net fusion energy in the lab to a working fusion generator. To get a head start on the problem LPPFusion investor Jerry Black has teamed up with fellow…

Preparations for Beryllium, Boron Experiments

LPP Fusion LOGO

LPPF is preparing actively for both the experiments with beryllium electrodes expected in the spring and for the shift to hydrogen-boron fuel expected before year-end. The research team is planning the new vacuum system that will ensure that any beryllium dust the machine produces will be safely trapped in filters. As well, efforts are underway…

Former US Fusion Chief Hirsch Advocates pB11 in Physics Today

Dr. Robert L Hirsch

Former director of the U.S. fusion energy program Robert L. Hirsch advocated moving research efforts to “a much cleaner fusion reaction”—hydrogen-boron (pB11)—in a letter to the editor published by Physics Today, the widely-read popular journal for the American Physical Society. In a major contribution to the debate on the direction of governmental fusion research programs,…
