What a refreshingly clear and thought-out plan. This project honestly gives me a lot of hope.

  Yes. Now it can be done, but costs too much. Once they get a scanning unit near the scrolls, it will be much cheaper. The data reduction will probably get cheaper, too.

    Scanning unit? Seems like the scanning was done using a synchrotron beamline. Maybe there is a suitable beamline at Elettra. I haven't looked closely why the synchrotron is needed. A Sigray instrument might work here, or even something simpler.

      Vesuvius Challenge used the DLS I12 "High resolution imaging camera" mode: https://www.diamond.ac.uk/Instruments/Imaging-and-Microscopy/I12/Detectors-at-I12.html https://www.diamond.ac.uk/Instruments/Imaging-and-Microscopy... https://drive.google.com/file/d/1I6JNrR6A9pMdANbn6uAuXbcDNwjk8qZ2/view?pli=1 https://drive.google.com/file/d/1I6JNrR6A9pMdANbn6uAuXbcDNwj... The 2019 scans were done at 7.91 micrometer resolution with 88KeV monochromatic x-rays. Synchrotrons like DLS can also use their uniquely coherent x-rays to do diffraction imaging but I see no evidence they've tried that with Vesuvius scrolls. (Because the object is too thick?) That scan is 5.5 terabytes of .tif files. The 2023 scan apparently is at 3.24 micrometer resolution and four separate scans of 53/70/88/105KeV each, which should produce a vast, data processing-chokingly wad of data. If all x thousand scrolls need to be scanned at that detail then the Vesuvius Challenge people are going to be juggling a lot of hard drives.
