21. Electrons generate the synchrotron radiation that is used at the end stations of beamlines. 22. Quantum Detectors was originally a spin out from the Synchrotron Radiation Source at Daresbury. 23. A great number of such beamlines can emerge from modern third-generation synchrotron radiation sources. 24. These relativistic electrons are detected as synchrotron radiation in the x-ray and radio wavelengths. 25. A sister process to the synchrotron radiation is the Thomson scatter them to high energies. 26. The blue synchrotron radiation contrasts with the yellow starlight from the host galaxy . ]] 27. The light source can be a laser, a discharge tube, or a synchrotron radiation source. 28. There is no way of determining the particle content directly from observations of synchrotron radiation . 29. Photoemission spectra are also measured using synchrotron radiation sources. 30. These stray electrons can be photo-electrons from synchrotron radiation or electrons from ionized gas molecules.
