synchrotron

They took their own sample from that core and conducted a number of tests, including examining a rock sample with a synchrotron—a very, very bright source of light, especially X-rays.

To actually look into the ice, the scientists took their anvils and samples to Argonne National Laboratory in suburban Chicago to use a synchrotron, a machine that can produce strikingly bright X-rays.

To peek inside a coprolite from Poland, the researchers used a synchrotron.

The synchrotron scan revealed whole beetle fossils that rival the quality of similar specimens in amber, along with fragments of the same kind of beetle.

Curious whether much older, fossilized poop could match the fossil quality of amber specimens, Qvarnström and colleagues used a synchrotron, which generates powerful X-rays, to peek inside a coprolite from Poland.
