Bending magnet radiation

Undulator parameters as of October 2003. Ef is the undulator fundamental, Ec the critical energy of the bending magnet radiation in the "slalom" motion. ... 

For bending magnet radiation, the natural opening angle (the total angle required... 

Figure 3.2 Comparison of the emitted power from two different synchrotron storage ring NSLS at 0.8 GeV, and SOLEIL at 2.75 GeV, with that of a blackbody at 2000 K. For SR, bending magnet radiation is considered, with collection angles of 40 mrad x 40 mrad (horizontal x vertical).

Water-cooled absorbers and masks are placed in the beam line front end. There are fixed and movable masks. A fixed mask is located next to the bending magnet vacuum chamber it constrains the opening fan of bending magnet radiation. The movable masks are the personnel safety...

Extended X-ray Absorption Fine Structure (EXAFS) the measurements were mostly made at the Gilda Italian Beamline (equipped with a bending magnet) at the European Synchrotron Radiation Facility in Grenoble (France). 

Polarization. The central cone of the synchrotron beam from a bending magnet and, in general, the beam from insertion devices is polarized in the plane of the orbit (i.e., horizontally). Due to relativistic effects the cone of the radiation characteristics is narrow even if the beam is emitted from a bending magnet (cf. [10], p. 9-13 and Sect. 2.2.2). If necessary, polarization correction should be carried out directly at the synchrotron radiation facility by means of the locally available computer programs. 

The X-ray source may be a conventional sealed tube or rotating anode generator or bending magnet synchrotron radiation and more recently the exploitation of multipole insertion devices such as wigglers and undulators represent great gains in source intensity.

Synchrotron radiation produced by a bending magnet is linearly polarized in the orbit plane of electrons (or positrons) and actually the term pj(e) of polarization dependence in formula (2) is equal to 3 for K edges where...
