Fusion gain has been demonstrated for the first time!!! The NIF shot from the 5th of December 2022 had a 300 MJ wall plug input for a 2.05 MJ laser output and 3.15 MJ of fusion yield. So the Q value was about 1,5. It was reported that the fuel burn up rate in this shot was about 4 %. The NIF team wi...

18 months runtime - but how many runs? In production, even at 1Hz, the number of runs will mount very fast. Where are they really? On a very general level HE states in their FAQ that: Helion's 7th fusion prototype, Polaris, will demonstrate net electricity from fusion, and will also demonstrate hel...

The Large Hadron Collider accelerates protons and heavier nuclei, but not antiprotons.

The article is sparse on technical details. It would have been nice with some numbers about the length of the devices and the energies reached.

I will point out once again, Helion is not just making Polaris to prove net electric power from fusion, they are making a fusion electric power generator FACTORY. Who else is so forward looking? Helion is accelerating commercial fusion in a real way. Not just about science, engineering, but generat...

The abstracts for the 64th Annual Meeting of the APS Division of Plasma Physics taking place October 17-21, 2022 in Spokane, Washington are available at [url]]https://meetings.aps.org/Meeting/DPP22/[/url. General Fusion, TAE Technologies and Zap Energy have several contributions to this conference a...

Previously General Fusion was targeting 2025 as the year when their Fusion Demonstration Plant (FDP) would start operating. For some reason GF now states on their homepage that the FDP start of operations will happen in 2027. The delay is of course unfortunate but hopefully Zap Energy and Helion Ene...

It is about ten months since Ladajo mentioned simulation work going on at EMC2. I guess we just need to be patient and one day we might have some more news on EMC2?

LPPF has struggled with arcing in their HV-switches and they describe their plans to mitigate arcing in their latest newsletter. https://www.lppfusion.com/storage/LPPFu ... 0-2022.pdf

In the contributions of the 20th US-Japan Workshop on Fusion Neutron Sources for Nuclear Assay and Alternate Applications at https://blog.umd.edu/iecf/posterspresentations/ it is reported that the University of Wisconsin-Madision IECF-group managed to their Homer fusor at 200 kV. See these two prese...

The final version of this paper has been published in Physics of Plasmas as open access, so it can be downloaded here: https://doi.org/10.1063/5.0083990 .

Avalanche Energy is discussed in this thread: https://www.talk-polywell.org/bb/viewto ... =10&t=6514.

The article in GeekWire mentions them aiming for 600 kV, which is indeed quite a lot. The University of Wisconsin-Madison IEC has worked on building fusors reaching 300 kV, https://fti.neep.wisc.edu/fti.neep.wisc.edu/presentations/bonomo_iec2012.pdf . That presentation is already ten years old, so I...
