Preparations Advance for Next Round of Tungsten Experiments

LPP Fusion LOGO

For the past month, the research team has been preparing for a second and final series of experiments with the two tungsten electrodes, before moving on to the planned combination of tungsten cathode and beryllium anode later in the fall (see next story). In the course of these preparations, we’ve come across a possible route…

FF-1 Shots Put 12 kJ into Pinch Region, Needs 3D Modeling Help to Go Higher

LPP Fusion LOGO

A new analysis of LPPFusion’s experimental results with the FF-1 device shows that fully 20% of the input energy was concentrated into the pinch region, where fusion reactions occur. As much as 12 kJ out of the capacitor bank’s initial 60 kJ was compressed into the pinch. These results, obtained in June with tungsten electrodes…

Hydrogen-Boron Groups Announce Advances, Plan Closer Collaboration

Hydrogen-boron (pB11) fuel has long been the ideal fusion fuel, offering the potential for cheap energy through direct conversion with no radioactive waste, as LPPFusion has often pointed out. But until recently only one or two researchers reported on results at any conference, while most focused on the far more common deuterium-tritium or pure deuterium…

LPP Fusion Reports Ion Energy Records, Other Progress to International Plasma Symposium

LPP Fusion’s President and Chief Scientist Eric Lerner reported on June 21 new record ion energies of over 260 keV (equivalent to a temperature of over 2.8 billion degrees K) to 150 plasma scientists assembled in Prague, Czech Republic for the 27th International Symposium on Plasma Physics and Technology. The new results, obtained with the…

Fusion Yield Up Almost 50% as FF-1 Resumes Firing

Six weeks after resuming firing, FF-1’s fusion yield reached 0.25 J on May 23, a nearly 50% increase over the highest-yield shot previously achieved with this device. This increase, confirmed by a second shot on May 24, provides the most concrete evidence yet that our continuing effort to reduce impurities in FF-1 increases fusion yield….

Preionization Tests Prepare for New Shots

The second main source of impurities in previous FF-1 shots has been vaporization of the anode material by runaway electrons. These high-energy electrons occur very early in the pulse, when the plasma has not yet become fully ionized—in other words, when only a few electrons are free to move outside of atoms. The cure for…

Bake-Out Succeeds in Cleaning Up FF-1

LPP Fusion’s research team successfully completed the bake-out of the FF-1 experimental fusion device during March, reducing the oxygen in the device by about a thousand-fold. The oxygen had been an obstacle in reducing impurities in the plasma that produces fusion reactions, because tungsten oxide and its compounds with hydrogen are easily evaporated into the…

FF-1 Moves Toward “Goldilocks” Bake-Out

LPP Fusion LOGO

LPPF Research Physicist Dr. Syed Hassan and Chief Scientist Eric J. Lerner continue to prepare FF-1 for the next set of experiments, which aim to rid the device of oxygen that has caused continued high impurity levels. A key step to doing this is a “bake-out” that heats the vacuum chamber and electrodes to drive…

Beryllium Arrives for New Electrodes

Two cylinders of nearly pure beryllium metal were delivered to LPPFusion’s Middlesex, NJ lab on January 14. The cylinders, weighing together 35 kg, are to be machined over the next five months into two anodes and a cathode for experiments in the second half of 2016. They were fabricated from 97.8% pure beryllium at the…
