You don't need to diffract the neutron flux. Instead, you can wrap (low-res) neutron-sensitive material around the stellarator tube. IDK now well would conventional photodiode or CCD work under high magnetic field, though.

That would just record the total neutron flux. It won't form an image unless you have a lens, aperture, or something similar.

It's almost as if you posit that the flux through every piece of surface is exactly the same. I suspect it's not.

No, total flux at a given location, not total flux in the whole device. The point is that it doesn't identify which direction the neutrons are coming from. That's why lens or apertures are needed.
