This book "Synchrotron Radiation Workshop" (SRW) is an open source physical optics computer code for calculation of detailed characteristics of Synchrotron Radiation (SR) generated by relativistic electrons in magnetic fields of arbitrary configuration. The powerful technique of synchrotron X-ray absorption spectroscopy (XAS) using tunable, very intense X-rays from a high-energy electron storage ring has been applied to investigate the structural properties of materials. Special relativity (SR) determines the properties of synchrotron radiation, but the corresponding mechanisms are frequently misunderstood. XAS is particularly attractive because of its ability to deliver electronic structure as well as geometric information. Free electrons can emit more power than bound electrons --> high ux The control of the electron beam trajectories in the storage ring is very sophisticated: small transverse beam cross section --> small photon source size Relativity drastically reduces the angular divergence of the emitted synchrotron radiation Synchrotron Radiation (SR) presents itself as a "play-ground" with a large range of methods and techniques suitable to unveil the mysteries of life. for tailoring properties of synchrotron radiation to the specific needs of the experiment.

Electrons ejected by X-rays from As the speed of the particle approaches the speed of light, the radiation pattern is distorted by relativistic effects and changes to a narrow cone of radiation, called Synchrotron Radiation. Classically, any charged particle which moves in a curved path or is accelerated in a straight-line path will emit electromagnetic radiation.

A synchrotron is a type of circular particle accelerator. It works by accelerating charged particles (electrons) through sequences of magnets until they reach almost the speed of light. These fast-moving electrons produce very bright light, called synchrotron light. Synchrotron radiation in a static homogeneous magnetic field is considered from the viewpoint of inverse Compton scattering of equivalent photons in a generalization of the Fermi-Weizscker-Williams method.
