Story summary

Researchers have developed a concept for a tabletop particle accelerator that could produce intense X-rays using carbon nanotubes and laser light.
The ultra-compact device could replace large, costly synchrotron facilities, potentially transforming medicine and materials science.
A study accepted for publication in Physical Review Letters shows circularly polarized laser pulses can accelerate electrons within nanotubes, generating coherent high-energy X-rays, though the approach remains in simulation.
