> We xray on what is AFAIK literally the most powerful xray beamline in the world and we would still like for it to be more powerful and faster.

What makes power relevent here? Obviously medical applications aren't particulary powerful, are quick, and are very useful. Is it harder to penetrate the material than the human body? Is the increased power due to increased resolution - i.e., increased pixels/cm^2 rather than increased watts/pixel? The latter would seem to risk damaging the artifact?

We scan the full scrolls a 2.4 micron and scan portions of them at up to .5 micron. This is 1000x to 4000x higher resolution than your standard medical CT scanner, so that requires a lot more power to get readings at such high resolution. There are other properties that make large synchrotrons more amenable to our task but I am not an xray technician so am not qualified to speak to most of them.

Damage to the artifacts is less than you might expect. I think that the radiation is particulary dangerous to living tissue and fiber. The scrolls are inert, pure carbon charcoal bricks for the most part and not particularly vulnerable to high power xrays.
