Structural biology Plasma
This figure shows a picture of electrons. Passing through the ondulator, electrons begin to deviate periodically from the beam direction, experiencing acceleration and emitting X-ray radiation. Since all electrons move the same way, radiation is enhanced by the fact that other beam electrons begin to absorb and re-eit X-ray waves of the same frequency. All electrons emit radiation synchronously in the form of a heavy-duty and very short flash (lasting less than 100 femtoseconds). The power of the X-ray is so high that one short flash turns a small crystal into plasma, but in those few femtoseconds while the crystal is intact, you can get the highest quality image due to the high intensity and coherence of the beam.
@ekaterina-gribacheva Interestingly, and due to what the electrons begin to emit X-ray radiation, what happens to them?
X-ray radiation occurs when accelerated electrons, reaching the anode, "brake down", and part of their kinetic energy is converted into X-ray energy.
The rest of the energy of accelerated electrons is used to heat the anode (so it needs to be cooled).
