Maybe I'm misreading your comment, but you seem like you're talking about privatizing this research whereas the other commenter seems to be talking about public cuts leading to a reduction of research. Just because something gets cut doesn't mean it gets outsourced elsewhere.
I guess my point is that it's hard to simply cut research that's essential for certifying that the stockpile is safe and works. I'll avoid making any predictions, because who the hell knows what's going to happen, but I think dynamic imaging work may prove a tough target for DOGE.
Why not just rubber stamp the certification and save all that money?

#837mths? What unit is that. Did they mean 7μs resolution? How is that special? I see youtubers doing nanoseconds. edit: here is the important information in this article. > Scorpius is a new accelerator project planned for the Nevada National Security Site (NNSS) that will use an electron beam that can be broken into customized pulses to deliver x-rays and capture multiple images only hundreds of nanoseconds apart. So…
While we're nit-picking the title, what does the "real-time" part mean? How would it be different if it wasn't real-time?
Dictionary.com defines "real-time" like as, "the actual time during which a process or event occurs", eg "along with much of the country, he watched events unfolding in real time on TV". Or in the domain of Computing, "relating to a system in which input data is processed within milliseconds so that it is available virtually immediately as feedback to the process from which it is coming, e.g. a missile guidance system might have "real-time signal processing".
Neither definition work here. It seems like they took a sequence of pictures very quickly, and then, some time later, played them back at an enormously slowed-down rate.

#84Every time I read about one of the national labs doing this research, I wonder how much longer we will head about these. I feel fairly positive that DOGE's layoffs and budget cuts mean this output will fade away in time.
Labs like this also have huge black budget spending that we don't get to see.
I'm guessing we'll see more hidden spending in future as the nukes and the engineers that made them get older. its worth asking if they even work (in some countries arsenals at least)

Your framing of the question suggests you believe in ideology, because you're posing a purity based based on hypotheticals alone. Where is the actual data for DOGE, in any department doing science?
Show me someone without ideology and I'll sell you a clock in London

#87Do the images match the simulations?

The first line of the articles says "seven-millionths of a second", which would be 1/7μs or 0,14μs. They also mention that the camera shot 16 frames in that period, so that would be once every 0,00875μs or once every 8,75ns Youtubers are a couple of magnitudes away from that, AFAIK
The slow mo guys did a video [1] at 10 trillion FPS. They also recently did another video [2] at 5,000,000 FPS. Their other videos vary between 50,000 FPS and 850,000 FPS. Edit: They mention in [2] that the Phantom camera they have can go to a 95ns exposure up to 1,750,000 FPS. [1] https://www.youtube.com/watch?v=7Ys_yKGNFRQ&pp=ygUMc2xvdyBtb...

The 10 trillion FPS number comes from the fact that they’re taking advantage of a strobing effect in the light they’re filming, such that if the strobe is happening at (for example) 1000Hz, they can get a frame at time T, then a frame at time T + 1.00000000001ms, then T + 2.00000000002ms, and so on. Then you stitch it together and it looks like they’re a 10-trillionth of a second apart.
No camera is taking in 10 trillion frames of data per second.

That's a great way to always be right: just claim the data that disputes your position is non-existent.
Uh, this is easy to refute if the data exists.

Considering the platform is budget cuts (yet an increased deficit) and science denial, I'm going to rate this hypothetical "highly unlikely".
