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.

Lisa Stiffler has written on GeekWire an article about Helion Energy, but Zap Energy and Avalanche Fusion are also mentioned:

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...

Helion has given an IAEA talk here: https://nucleus.iaea.org/sites/fusionpo ... inars.aspx. The presentation gives the current status of the Polaris activities and shows nice pictures of their previous experiments.

Here is a ZAP Energy presentation from last year which has some new details at least for me: Fusion Energy on the Horizon, https://apec-conf.org/wp-content/upload ... orizon.pdf.

GF has a nice summary of their latest achievements now that they will try to start compressing plasmas with LM26: All systems go! LM26 ready to compress plasmas, https://generalfusion.com/post/all-syst ... s-plasmas/.

Yes, it is nice to see that their hard work is starting to pay off.

They haven’t started compressing the plasmas yet, just injecting them into the LM-26 chamber. FYI, LM-26 has a lithium shell which will collapse by using massive current flow to the external coils. The spheromack topology FRC plasma is supposed to adiabatically collapse (GM has proven in tests), th...

General Fusion has created the first plasma in LM26 and they are by now forming plasmas daily in LM26.
