Re: National Ignition Facility
I Was NiF ever imagined to be practical? In my "I am not a physicist" ignorance it always seemed silly -- all those acres of amplifiers and capacitors all focusing multiple lasers on a teeny weensy dot, and then one shot at a time. Even if that dot (well, hohlraum) could be rapidly replaced, and ev...

Re: National Ignition Facility
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...

Re: Helion Energy to demonstrate net electricity production by 2024
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...

Re: Electron gun 2022
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.

Re: Helion Energy to demonstrate net electricity production by 2024
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...

Re: General Fusion in the news
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...
Re: EMC2 news
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?
