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

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…
