A full sequence of images of the current sheath of LPPFusion’s #FF2B 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 shock waves.

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.

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 upgrades in the fall. This will allow us to keep to our plan of initiating experiments with hydrogen-boron fuel in 2020.

Had a great visit from one of our investors. It was great fun showing Jeff around and answering his questions.

He also took the opportunity to demonstrate to us his massage device...our sysadmin's first experience with one.

No pictures of that...you'll have to take our word for it. 😂

We're starting a new fundraiser for LPPFusion on GoFundMe, while continuing on Wefunder. If you have $1,000 to invest, do that on Wefunder. If you can't spare $1,000, give us any amount on GoFundMe. You'll get a chance to help us to a cleaner, safer world.

However, we are working hard to eliminate the oscillations so there is a single front and the filaments will be neatly organized all the way to the front of the sheath.

These images are produced from 10 separate, but very similar, shots. The flickers in brightness are caused by changes in camera filters and sensitivity—the real brightness is steadily increasing during the time covered as the current flowing through the sheath increases.

But the images also show the challenge that we currently face—the front (right) edge of the sheath is not a single, sharp line, but two separated fronts. This is caused, we know, by the oscillation in current that produces an early small pulse of current, followed by a bigger one. In the region between the fronts the filaments are twisted and disorganized. This leads to poor compression and less fusion.

They show the development of the sheath from 230-570 ns after the current starts flowing. So the events are happening about 6 million times faster than you see them in this GIF. The key positive features of the images are that the filaments (running from lower left towards upper right) are evenly spaced and thin—only 200 microns in radius. Those characteristics should lead to a dense plasmoid and rapid fusion burn.

The images, taken with our ICCD camera using an exposure time of only 5 ns (billionths of a second) show the current sheath moving down the anode (towards upper right) as viewed between the cathode vanes (diagonal black bands). The top-to-bottom size of the images is 2.5 cm.

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.
