They have been using "edge-biasing" NBI since C-2U in 2015.

I've not heard him called that before.

also doing test runs

Also known as commissioning and integration.

Andrew Proffitt, a guy with 14 years of experience working at the NRC, says they are doing commissioning and integration of Polaris.

Neutral Beam Injection is not cheap.

Thanks for the specifics on the plasma. GM did a lot of testing to find the right geometry for the plasma. Creating the right plasma dynamic shape in their injector that enables the plasma to retain geometry during adiabatic compression is a feat. Amazing work.

Who is GM?

https://www.zapenergy.com//news/doe-century-milestone basically ZAPs DEMO machine is online. The commercial race is real. Century is not doing fusion. After FuZE-Q, their next fusion device will be FuZE-L, a liquid metal wall version of FuZE. It is planned for the same building as Century, but Cent...

Dividing the vacuum vessel into only two halves sounds much better than the segmented architecture shown in their earlier paper - requiring only two welds instead of 18. I'd like to see what their tooling looks like. I'm envisioning a semicircular cradle for each half of the vacuum vessel, with a s...

I can tell that she did not read the paper because of the things she said.

What things did she say?

Hossenfelder did not even bother to read their recent paper. Helion did publish results for Trenta. I see what you did there. We don't know if she read their recent paper, but that is moot because it had no experimental results. What you meant to say is that Sabine did not attend the American physi...

They are testing low-temperature solders for demountable magnets for ARC. The idea is to melt the solder in the joints without melting the solder in the rest of the magnet. https://iopscience.iop.org/article/10.1088/1361-6668/ad0b2b/meta I don't think ARC works without demountable magnets, but the e...

Aside from the obvious statement that they are looking for new, better materials for their magnets, it also re- affirms that Polaris is operational. I suppose that this is meant to address the claims to the contrary made by some people (citing permits). I felt I should respond to this. Maybe this i...
