synchrotron radiation ppt

Coherent synchrotron radiation (CSR) is produced when a group of electrons collectively emit photons in phase. However, most of this radiation originates from a very small region of the particles orbit near the origin of the above coordinate system. The synchrotron radiation will contribute the heat load to the beam pipe and cause the photon background to the experiments. e-mail : barrett@esrf.fr.
