Here is a sample lab-generated X-ray spectra for the NIST 610 standard, used for one of the 4 disks in the PIXL calibration disk.

Joking, hinting or criticizing is not only welcome but necessary to keep some balance 🙂

Tried to find ways to present PIXL images before, with questionable results (img). PIXL is a unique instrument, though not an easy one to engage with on a frequent basis. But its findings published in papers and presentations are eagerly awaited 🤓

Meanwhile, trying to ground sensation with maps and other technical info may be a middle way to create interest.
