LPP Fusion completed its third Wefunder crowdfunding campaign, raising $683,000 from 816 investors across 48 countries, two days after its first fusion shot of the year.
Electric Fusion Systems hired Voss Scientific to use their plasma simulation software to model EFS's unique aneutronic fusion reactor design.
LPPFusion received a new beryllium anode stalk at its Middlesex, NJ laboratory, which will be installed in the FF-2B device to carry current and withstand intense energy during fusion experiments. The anode will undergo annealing and oxide removal before re-assembly, with experiments expected to resume in May.
LPPFusion's Wefunder crowdfunding campaign raised over $300,000 in the first month from 375 investors across 19 countries, surpassing its initial $200,000 goal to fund ongoing research.
LPPFusion's research team has received all parts for new switches, and researcher Syed Hassan has begun assembling and testing 24 switches, with initial steps completed and further testing planned for upcoming experiments.
LPPFusion has launched its third crowdfunding campaign on Wefunder, starting on March 4, 2021, with a minimum investment reduced to $150 and a funding goal of $200,000.
LPP Fusion's engineer Rudy Fritsch completed the redesign of the anode stalk, optimizing the wall thickness and hole radius based on simulations, and sent new drawings to the manufacturer with an expected delivery in February 2021.
LPPFusion's research team has developed new simulations indicating a potential solution to the current oscillation problem that has limited fusion yield since mid-2019; a new snubber circuit design reduced simulated oscillations significantly, and experimental testing is planned.
LPP Fusion's mechanical engineer Rudy Fritch and chief scientist Eric Lerner used simulations to redesign the anode stalk for their fusion device, addressing previous cracking issues and analyzing heat and stress effects on the anode material.
LPP Fusion reports that new switch parts for their Focus Fusion generator, specifically 24 smaller switches, have started arriving at their lab in Middlesex, New Jersey, to improve the device's current capacity.
LPPFusion announced the start of manufacturing their new beryllium anode, including ordering its machining and receiving the beryllium metal, with plans to complete the anode by November 2020.
LPPFusion ordered beryllium material on June 25, 2020, to produce three anodes for their fusion experiments, with the first anode machining expected to be completed by November 2020.
LPP Fusion's researcher Dr. Warwick Dumas developed a new plasma simulation that models the early stages of the current sheath within plasma, distinguishing electron and ion behavior more accurately than traditional MHD models. The simulation has recently modeled the development of the current sheath for the first 220 nanoseconds of a pulse.
LPP Fusion's CIO, Ivy Karamitsos, completed a major IT upgrade funded by crowdfunding investments, costing just under $40,000, to improve their engineering and simulation capabilities. The upgrade includes new hardware, software, and a project data management system, supporting expanded use of simulations for upcoming experiments.
LPP Fusion's ICCD camera images show that shock waves likely cause filament disruption in their FF-2B fusion device, limiting energy yield; new switches are being developed to eliminate current oscillations and shocks.
LPP Fusion reports that using a beryllium anode significantly reduced electrode erosion compared to a tungsten anode after nearly 200 shots, with the beryllium surface remaining smooth and less roughened.
LPPFusion's research team discovered cracks in the anode of their Focus Fusion device in March 2020, leading to a redesign of the anode and switches. They plan to resume experiments with new components in the fall of 2020.
LPP Fusion reported that their FF-2B device recovered from a minor accident involving a power outage and vacuum system issues, with repairs underway to resume firing experiments by the end of March.
LPP Fusion's Wefunder crowdfunding campaign ended on March 1, 2020, having raised $605,000 from 292 investors across 22 countries, with additional funds raised through a Reg D offering.
The images from inside LPP Fusion's Focus-Fusion-2B device show the development of current filaments during plasma pulses, which are important for achieving fusion reactions; progress has been made in reducing current oscillations to improve plasma compression.
