Portable 1MV X-ray system combines Cockcroft–Walton with Van de Graaff dome

What is the equipment at [1] in the video? It looks like a huge room of large centrifugal blowers not connected to any ductwork. Is that some random AI-generated picture? From Los Alamos National Laboratory?

For comparison, here are some large centrifugal blowers from The New York Blower Company.[2] They're a standard industrial item, but unrelated to X-ray machines.

Very cool. I have a ~750 kV VDG that sits around gathering dust in the garage because it's such a pain to keep the moving parts aligned and running smoothly. Might have to retrofit it with a C-W stack.
