Right, but the method is used on Polaris for optimizing the DT-shots.

HE has published a paper on arXiv on their DT neutron measuring method with the title Fused-Silica Activation Cherenkov Detector for Pulsed D--T Fusion Yields.
https://arxiv.org/abs/2602.22477

Helion Energy has announced preliminary results of running five D-T pulses in Polaris and achieving a temperature of 13 keV. Very nice and interesting news!

Pacific Fusion has made experiments on the Sandia Z-machine and advanced their concept:

Avalanche Energy’s relatively small funding needs dovetails with their iterative speed ($29M!), but why the need for superconductors?

I guess it is because they confine the electrons magnetically. Using superconductors for that would improve the efficiency of their apparatus.

Avalanche Energy has gotten 29 MUSD in new funding. Their press release describes their accomplishments and plans. It also lists their most recent papers:

General Fusion has released news that they are going public: GENERAL FUSION TO BECOME FIRST PUBLICLY TRADED PURE-PLAY FUSION COMPANY THROUGH BUSINESS COMBINATION WITH SPRING VALLEY ACQUISITION CORP. III https://generalfusion.com/post/general-fusion-business-combination-announcement https://generalfu...

Avalanche has published a few papers since they left stealth mode. They have also presented at the 65th and 66th Annual Meetings of the APS Division of Plasma Physics in 2023 and 2024. This is the latest publication that I found: Hammerhead: a compact 300 kV vacuum bushing , https://doi.org/10.1038/...

The video is really interesting. I'm looking forward to hear results from their next experiments.

General Fusion has good and bad news. The good news is that the first LM26 plasma compression shot went OK. On April 29th, we achieved a transformative milestone at our Vancouver, B.C., headquarters in Canada—we successfully compressed a large-scale magnetized plasma with lithium using our world-fir...
