Vacuum Chamber gets Titanium Nitride Coating, New Window as Tests Near

As preparations for the next set of experiments accelerate, LPPFusion has received the newly coated vacuum chamber parts back from suppliers in Ohio and NJ. The parts have been coated with titanium nitride in order to minimize the oxygen in the chamber. On the one hand, the coating will act as a sponge soaking up…

Cooperation Aids Oxygen Elimination; Vacuum Chamber Getting Titanium Nitride Coating

With the help of scientific collaborators, LPPFusion’s team is moving towards eliminating the sources of oxygen in Focus Fusion-1’s vacuum chamber. The oxygen has been the key obstacle to progress in the experiment for the past several months. While the pure tungsten electrodes installed in June are highly resistant to being vaporized by the device’s…

Titanium Lining for Vacuum Chamber

To download this report click here Based on the results of test shots fired in September, LPPFusion’s research team has decided to line the vacuum chamber of the device with titanium or a titanium compound. While we cleaned oxides off the tungsten, these compounds have reappeared due to oxygen in the stainless steel chamber. After…

Oxides Removed From Tungsten Electrodes

oxide

As the research team had suspected, an oxide coating on the tungsten electrodes prevented the achievement in the first shots in June of the very low impurity levels needed for increased fusion yield. This oxide coating has now been substantially reduced or eliminated and the electrodes are ready for a new round of experiments. When…

Tungsten Cathode Arrives, FF-1 Re-Assembly Moves Forward

The new tungsten monolithic cathode, key to LPPFusion’s next set of experiments, arrived at our laboratory in Middlesex, NJ on Feb. 27. Careful acceptance tests confirmed that it is 99.95% pure tungsten and is within the 150 micron tolerances that we specified, a significant accomplishment by the manufacturer Tungsten Heavy Powder and their colleagues in…

Beryllium Electrodes Ordered, Import Application Submitted

beryllium

As we prepare to use the tungsten electrodes for the first time, LPPFusion is also preparing for the final set of electrodes, to be made from beryllium. The tungsten electrodes, with their extreme resistance to heat, will allow the tests needed to pave the way for the use of beryllium, which is a much more…
