Plasma Simulation Advances

Simulation-220.06-ns

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

LPP Fusion LOGO

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

Animation-230-to-1100-ns-with-Gray-Arrows

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

Beryllium-Anode-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

Syed-and-Eric-Removing-Anode

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…

Our Plan to Get to Net…Energy

Focus Fusion Generator – CAD Drawing

During the Wefunder campaign, people have asked us: how can we expect to go rapidly from where we are to net energy—when we get more energy out of the device than we put in? We gave them an explanation. Since many people have told us how useful this information is, we are featuring it in…

Images Catch FF-2B in Action

These new images from inside our Focus-Fusion-2B experimental device show the development of the filaments of current (bright thin parallel lines) in the early stages of each pulse. The filaments are a crucial step in compressing and heating the plasma to get fusion reactions. The images, taken with our ICCD camera using an exposure time…

X-rays Show: FF-2B’s Best Shot is All Hot!

The latest data from LPPFusion’s lab shows that all the plasma in our tiny fusion plasmoid is hot, not just some of it. Hot in this case means 600 million degrees K, sixty times hotter than the center of the sun. This new result shows that our results are being fairly compared with those of…

Plasma Focus Researchers Agree on Key Point

LPP Fusion LOGO

At a workshop in Warsaw, Poland, plasma focus researchers from around the world agreed on a key aspect of the functioning of the plasma focus device and clarified what we still disagree about. The key point we unanimously agreed on is that in plasma focus devices with large currents, the fusion reactions are caused by…
