Simulations, New Ideas Aid Anode Final Design

Liquid Like Waves in Be

LPPFusion Mechanical Engineer Rudy Fritch has continued to work with Chief Scientist Eric Lerner on simulations aimed at redesigning the anode stalk. These studies are critical to the next experiment, as the last anode cracked and the new one will be subject to greater currents produced by the new switches. Fritsch used SolidWorks CAD program…

New Switch Parts Start to Arrive


Parts for the new switches for FF-2B have now started to arrive at our lab in Middlesex, NJ. As explained in the last report, the biggest differences between the new switches and the existing switches are their number and size. Instead of one switch per capacitor in the old design, we will now have two…

New Anode Starts Manufacture

In a second step in our upgrade, LPPFusion has placed an order for the machining of the base of our new beryllium anode. We have also received a cylinder of beryllium that will be used for the shaft of the anode, so we now have all the beryllium metal that we need for machining. The…

Beryllium for New Anodes on Order

Beryllium Cathode Attached to the Support Structure

In a major step towards new experiments, LPPFusion placed an order June 25 for the beryllium needed for our new anodes. Materion, the US supplier of beryllium, has promised to produce the material by Aug. 7. The cylinder of beryllium will be enough to produce three anodes, although initially we will be ordering just one….

Plasma Simulation Advances


Another simulation LPPFusion is working on is modeling the early stages of the current sheath within the plasma. This original simulation software is being developed by LPPFusion Simulations Researcher Dr. Warwick Dumas. It differs from the most common plasma simulations, called MHD, in accurately distinguishing the way electrons and ions behave when they are moving…

Major Software Upgrades Aid Thermal, Mechanical Simulations


Our CIO, Ivy Karamitsos, carried out a major IT upgrade thanks to the Wefunder crowdfunding investments that we gained this March. The upgrade cost just under $40K, but it was a long overdue investment into our infrastructure as we needed improved in-house capabilities for our engineering drawing software and simulation productions. We also purchased SolidWorks…

ICCD Video Reveals Shocks


A full sequence of images of the current sheath of LPPFusion’s FF-2B experimental device shows that a shock wave is the most likely proximate cause of the disruption of filaments that has limited fusion energy yield. Our rapidly-advancing effort to provide new switches for FF-2B provides a path to eliminating the oscillations that cause these…

Beryllium Decreases Electrode Erosion


While the cracks were bad news, our inspection of the beryllium anode also brought good news. The erosion of the electrode near the insulator has markedly decreased with the beryllium electrode as compared with our previous tungsten electrode. This erosion and roughening, seen clearly in Figure 3a of our last tungsten anode caused an asymmetric…

Anode Cracks; Another Design on The Way


Just as the LPPFusion research team was about to resume firing in March, we discovered that FF-2B’s anode was cracked. We’ve used the shutdown time, necessitated by both the crack and the coronavirus, to complete the design of our new switches, and to redesign the anode. We’re aiming to resume firing with these crucial new…

FF-2B Recovers from Minor Accident

Be with Vacuum Chamber

While we would love to cheer our readers with some exciting news form the lab, this past month we have been held up by a minor accident and our (mostly successful) efforts to recover from it. On Jan. 20, at 4:00 AM, on a holiday, our lab suffered a brief power outage. Although all our…
