Upgraded Vacuum Chamber Designed and Ordered

LPPFusion Vacuum Chamber 3D Render

As part of LPPFusion’s preparations for our upcoming experiments with beryllium electrodes and pB11 fuel, we are upgrading our experimental equipment. Research Physicist Syed Hassan has completed a re-design of our vacuum chamber. The key change is to enlarge and reposition the viewing windows. The chamber will now have three six-inch windows, instead of just…

Thermal Study of Electrodes Begins

Initial Simulation of Heating of the Electrodes in FF-1

The cooling of the plasma focus electrodes, especially the anode, is likely to be the toughest engineering problem to be faced in going from a demonstration of net fusion energy in the lab to a working fusion generator. To get a head start on the problem LPPFusion investor Jerry Black has teamed up with fellow…

Preparations for Beryllium, Boron Experiments

LPP Fusion LOGO

LPPF is preparing actively for both the experiments with beryllium electrodes expected in the spring and for the shift to hydrogen-boron fuel expected before year-end. The research team is planning the new vacuum system that will ensure that any beryllium dust the machine produces will be safely trapped in filters. As well, efforts are underway…

Former US Fusion Chief Hirsch Advocates pB11 in Physics Today

Dr. Robert L Hirsch

Former director of the U.S. fusion energy program Robert L. Hirsch advocated moving research efforts to “a much cleaner fusion reaction”—hydrogen-boron (pB11)—in a letter to the editor published by Physics Today, the widely-read popular journal for the American Physical Society. In a major contribution to the debate on the direction of governmental fusion research programs,…

Two More DPF Groups Aim to Use pB11 in 2018

Two dense plasma focus teams in Poland plan to use hydrogen-boron fuels in their experiments in 2018. This will mean that, including the planned experiments with LPPF’s FF-1 device there will be three devices simultaneously experimenting, for the first time, with the combination of DPF and pB11 that LPPF has long called ”Focus Fusion”. The…

Microwave Power is Up, Testing Still Underway

Based on tests conducted in May, the LPPFusion research team decided that more microwave power was needed to clean the oxides off our tungsten electrodes. The oxides, which break up easily when heated, had been contributing impurities to the plasma and limiting fusion yield. We decided to mount two kW microwave magnetrons on a single…

Beryllium Cathode Arrives

The long-awaited beryllium cathode arrived at LPPFusion’s Middlesex lab on August 18. Since the beryllium anodes have been in hand for some months, this completes the delivery of the electrodes that are needed for the next crucial step in the Focus Fusion experimental program. This will be the first time beryllium electrodes are used in…

Beryllium Cathode Nears Completion

Hardric Labs in Massachusetts has reported to LPPFusion that its work on machining the new beryllium cathode (fig.4) is nearing completion and they expect to ship the finished piece in early March, only a few weeks behind their initial schedule. Since the beryllium anodes have already been received at the Middlesex NJ lab, we will…
