LPPFusion completed assembly and testing of 16 redesigned dual switches on its FF-2B experimental fusion device, achieving a 25% increase in peak current compared to previous designs and reducing current oscillations.
LPPFusion announced that it has reached its March 2023 fundraising goal of $100,000, with $102,000 in pledged investments as of April 6, 2023, and plans to accept further investments from accredited and non-accredited investors.
Startorus Fusion held a signing ceremony in Jiading, Shanghai, after completing a Series A financing round of 1 billion yuan to develop its controlled nuclear fusion technology and build a demonstration reactor by around 2032.
LPP Fusion's board of advisors extended the company's existing Reg D share offering until June 30, 2023, with a new crowdfunding campaign planned for March at the same share price, to raise funds for laboratory progress.
LPPFusion completed control tests and began assembly of new small switches for their fusion research, with initial tests of the new switches expected in March 2023. The previous switches showed deterioration due to adhesive contamination, affecting their performance.
LPPFusion published a paper in the Journal of Fusion Energy demonstrating that their experiments have achieved the highest fusion energy generation to device energy input ratio and the highest n tT product among private fusion efforts, with peer review confirming their leading results.
The Wefunder crowdfunding campaign for LPP Fusion ended on December 9, 2022, raising $316,520 from 386 investors, which was half of their previous year's amount and below their $100,000 monthly goal. They plan to restart crowdfunding on StartEngine and seek larger investors.
LPP Fusion reported that their switch testing for the FF-2B fusion device has successfully ended, with the switches demonstrating repeatable synchronous firing at 5 nanoseconds and eliminating previous issues such as pre-fires and surface flashovers. They plan to resume firing in January 2023.
The Focus Fusion Society awarded LPPFusion an additional $81,000 grant for research on hydrogen-boron fusion using the dense plasma focus device, supplementing previous funding and supporting specific testing and design efforts.
LPPFusion reported that their continued testing of dual switches demonstrated increased current when firing simultaneously and a reduction of the negative pulse by a factor of three, with further tests pending due to delayed parts delivery.
LPPFusion reports progress in developing a two-layer Kapton and Teflon armor to prevent undesired switch breakdowns in their fusion device, with testing expected to resume in November after applying the design to the top electrode.
Ignition Computing, along with an international consortium, has received a service contract to develop and support software for modeling and analyzing ITER's plasmas, which will aid in predictive simulations and data interpretation for the fusion reactor under construction in France.
LPP Fusion reported preliminary success in testing a redesigned switch for their fusion device, demonstrating that a proper seal of the Teflon insulator can eliminate surface breakdowns and enable consistent firing at 40kV.
Electric Fusion Systems announced the filing of a patent for their novel fusion reactor, which operates using a critically dense liquid metal/hydrogen environment and employs an oscillating, cyclical design to achieve aneutronic proton-lithium fusion.
LPPFusion launched a 2022 Wefunder crowdfunding campaign on June 21, 2022, to raise between $200,000 and $5 million for fusion research, increasing its share price to $200 and its valuation to $64.8 million.
LPPFusion began testing switches with Teflon insulators in April 2022 to improve resistance to surface breakdown; redesigns are underway to achieve a 45-degree triple-point angle to prevent flashover, with new tests expected in August.
LPPFusion's research team achieved a new world record for plasma purity in their FF-2B device, reducing impurity levels to less than 0.2% of ions in the fusion region, which is at least ten times lower than any other fusion device reported.
LPPFusion reported that their FF-2B experimental fusion device's new switches are taking longer to optimize due to firing synchronization issues and negative current pulses, but the team has identified problems and solutions related to switch triggering and insulator materials.
Helion announced it has raised $500 million in funding, led by Sam Altman, to build its fusion demonstration generator Polaris, which aims to produce net electricity from fusion in 2024.
LPP Fusion's research team began new experiments with their FF-2B fusion device on August 4, achieving a sixfold reduction in anode erosion and an 8% increase in peak electrical current compared to previous results.
