The ray of light, in order to maximize efficiency, seems to know where it's going from the start.
Most trematode eggs require oxygen in order to form the first larval stages and light in order to hatch.
This facility utilizes intra-cavity back-scattering of the FEL light in order to produce intense γ-ray beams.
